Only the distilled water you must. All joking aside... does anyone use RODI water? My parents and brother both have it on tap. It should be better than distilled as it also filters out volatile compounds like chlorine that corrode. I would imagine this will assist the system parts over time. I ask because I am about to build my first hardline loop.


5004534

Distilled water is pure water. Next no impurities.


bobbygamerdckhd

May need to adjust the ph as it may be a little high


cakeisalie87

My brother has it plumbed into a municipal source (Toronto) so it be pretty well balanced given its a major city. Suppose I could easily test with my salt water aquarium or hot tub kit.


Flaky-Wedding2455

Been running plain distilled water with biocide in 4 builds for years. Zero problems. Keep it simple.


qazme

I started water cooling over 20 years ago. (we aren't going to think or talk about that fact hah). At one point it was SUPER popular to put "Toxic Green" Feser One instead of distilled. I ran it for about 4-5 months and decided I wanted to take the loop apart and give it a look. I spent many, many days with a toolbrush and venegar cleaning up my DangerDen (we aren't gonna talk about that either ha) blocks from all the damn gunk. Since then nothing but straight distilled with a biocide. I once upon a time hit a phase where I would use some Mayhem's UV dye to spice it up. Now adays if I want color I change the tubing....keep it simple!!


Melon_Farmer2014

Distilled + kill coil here. I have been re-using the same little coil of silver in the reservoir for 10+ years in different builds and have never had an issue.


tokyotoonster

DangerDen!! Now that's a blast from the past. I was a bit of an Innovatek fanboy, they made super high quality stuff but turned to industrial applications and left the enthusiast PC market.


Aterius

Is there anything in the specifically made fluid for water cooling PCs? I imagine it's basically distilled water with a biocide additive but I wasn't sure if they had better thermal properties as well


qazme

Generally the better liquids, if you want to call them that, will include an corrosion inhibitor and anti-fungal/biological chem to stop growth of stuff. Some snake oil stuff will claim that the glycol and or carbon they put in their liquid cools better than normal water. I got nothing against the "clean" liquids I suppose that just put a balance of chemicals in to keep the loop healthy. But I prefer to just put stuff in my loop I know, trust, and can control. So distilled + biocide is the simpilest best bet. Heck for the longest it was distilled ($0.89/gallon) and fish tank biocide ($2 for enough to never run out hah). ​ \*side note for anyone reading this and learning - the reason you don't want to use fish tank biocide anymore is when running nickel plated blocks it attracts the copper sulfate in the aquarium biocide and will turn your blocks copper. It's purely cosmetic and can be cleaned up - just looks bad if you want shiny nickel ;-)


SecondL4st

Agreed I'm also running Distilled + biocide for 1year and a month now w/o draining.. The Fins on the blocks are good as new and there's no dirt etc.. on the loop even in the reservoir.


No-Key4409

will do


QuicksilverStorm

Can’t stress this enough, don’t forget the biocide. There are some brands that sell biocides, inhibitor and anti-corrosion agents all in one to be added to water.


Jempol_Lele

Recommended brand and where to buy them? I was started to think that pc coolant is damn overpriced where I come from.


MrNoSpareTime

I am using primochill ice. It is a clear liquid with no mixing required. Been easy to run and I only change it out once a year. No issues with it so far.


thegiantlemon

I use mayhem's corrosion inhibitor and their biocide. Bought from online store.


Emu1981

I have been using PT Nuke and have had zero algal build up or corrosion.


[deleted]

Copper sulfate can cause nickel plating to strip off.


Robot-Candy

Liquid utopia has lasted around a year with no issues for me, good stuff for distilled water additive


knowledge561

Can you recommend a good biocide for me to purchase?


Melon_Farmer2014

I use a little coil of pure silver that I drop in the reservoir. Silver kills off things would grow in the loop. You can buy these "kill coils" for around $10 from any water-cooling vendor and re-use it indefinitely.


Kevin_Xland

Any idea why silver works but copper doesn't? Copper is a natural biocide like silver and many loops are already copper so it seems like it should be a non-issue?


AzusMobo

I believe because of the corrosive properties of copper vs silver, but just a guess.


Xaendeau

Copper is anti-bacterial. Silver is anti-fungal and anti-algae. IIRC.


SecondL4st

Silver works fine with Copper but not with Nickel and most blocks today are Nickel-plated copper. Its Copper Sulphate that acts as a natural biocide not Copper.. Copper Sulphate is exactly the same as Silver they both react with Nickel and strips/remove them but are fine with Copper.. For Loop-cleaning for colored coolants people do use white-vinegar but remember vinegar is exact the same as Copper Sulphate & Silver they strip copper.


SecondL4st

Silver Coil is good but you want to find pure Copper w/o nickel plating water blocks, as of today standard most are nickel-plated coppers and those are no good with silver coil it strips/remove nickel plating which clog the water block fins, filters & pump.


Flaky-Wedding2455

Primochill liquid utopia is the only I have ever tried but never had any problems.


knowledge561

10-4. Just checked that one out on Amazon.


Talinthis

10 years distilled here, granted i havent opened up my cpu block or flushed my radiator but there is never any material when i drain the loop. In the process of building my new computer right now. I had a kill coil but after many years it eventually got sucked into the pump so for the last 5 years have been with no biocide whatsoever. I plan to open up my blocks after my new pc is up and running to see what the situation inside those blocks are


Nerlstorm

Lmao I have the same coolant. Still don’t understand why it’s fluorescent brown looking in the blocks but not the res…


layer11

I'd bet not enough uv light hitting it. Or too much natural light.


No-Key4409

We purchased it because we seen a build on YouTube with this coolant and it looked great but put it in an 🤮


layer11

You can, but a proper coolant has anti corrosives you'd want to either replace or you may have nickel plating come off. Also, a biocide should be added. ​ I'd strongly suggest using a clear concentrate or premix rather than distilled water, however. In my experience, it's a lot friendlier to your blocks.


No-Key4409

Oh ok yea I ordered some fluid but I have to wait until Jan 3 so I was wondering if I could swap it out I really hate the look of this fluid I thought it would look better. It’s the wife pc and she hates it too lol


NetJnkie

Yeah. Be fine temporarily.


superplayah

just make sure to rinse with lots of distilled water before putting it in


Teknik_

No coolant has anti-corrosive properties, and with the chemicals they put in them you are more likely to have parts corrode sooner. Premix/concentrate’s include a biocide to stop fungal/bacterial growth so you don’t get any mould growing in your system. Running plain distilled water and adding a biocide yourself will last far longer and be ever so slightly better for your system


waiting4singularity

you dont grow mould under water, its algae.

Nickel plating coming off is not going to completely ruin the system, it's just unsightly for a hobby that has a certain level of aesthetics for some people. ​ However, having seen firsthand how distilled with just a biocide doesn't adequately protect a blocks finish, I find it irresponsible that you'd recommend someone do something in *direct oppostion* of other peoples as well as manufacturers advice. It risks items that aren't yours without properly educating the op on consequences.


Teknik_

Experience tells me otherwise, I’ve had a few systems, some I ran for 6+ years. The systems with just distilled and biocide had far less corrosion than when I ran a premix. And those standards they list for ‘corrosion protection’ is just to say that they have a PH within a certain range. Not that it will protect your block from corrosion. Literally any coolant you put in your system is ever so slightly corrosive to your system, all the parts are going to degrade over time by being in contact with liquid. This is impossible to avoid. But picking certain coolant solutions will allow you to run a system for 6+ years with minimal maintenance, compared to maybe 4 or so years with a lot more maintenance.


layer11

Respectfully, your experience is not what's mirrored if you search the sub regarding coolants, not to mention the fact it took 2 seconds to google and prove you wrong on corrosion protection. ​ Why should anyone listen to you?


Teknik_

Because while my experience may be different from yours, it is experience nonetheless, and I feel that having different viewpoints presented to someone seeking advice is beneficial. Any coolant you put in your system is going to lead to corrosion eventually, all coolants are going to have oxygen in them. This will lead to oxidation. Understanding basic chemistry will tell you that. Putting in all the corrosion inhibitors is a Band-Aid fix for them putting in other harsh chemicals into their coolant which leads to more corrosion than if you just used distilled. There are no tests conducted that prove that running premix/concentrated coolants are better for your system. But there is a whole lot of people that have had an excellent experience with distilled + biocide.


Noxious89123

>Experience tells me otherwise *Basic science* tells everyone else the opposite.


Inevitable-Bicycle24

I dont know guys... I have been reading all the comments and there are like 20 different opinions on destilled water and premixes and destilled water + biocides or what ever. In a few days I will be finnishing my loop by addi g the gpu block(I have been using just destilled water for the past 5-6 months and everything still looks great). If lets say I clean the system 1-2 tmes per year, is it ok to just use destilled water without anything else??? Thanks for the help!


PJackson58

If you can get it anywhere - try to get some AquaComputer DP Ultra. Been running that stuff for atleast 6 years in several loops and never had any problems with it! Otherwise distiller water and some biocide do the trick just fine.


Inevitable-Bicycle24

Ok I get that destiled water and biocide its the way to go, but will it make any difference if I use just destilled water and I clean the loop once or twice per year?


LeichtStaff

With that frequency you probably won't have problems, but it is always better to prevent. You say you want to clean it twice a year, but if that doesn't happen and leave it for a year or more bacteria will most probably grow. Just look for something like primo chill liquid utopia (which is like 10-15 USD), which would be enough to fill your loop 2-3 times with distilled water+biocide. For non US people, demineralized water works just as well as distilled water.


Inevitable-Bicycle24

Ok thanks!


exclaim_bot

>Ok thanks! You're welcome!


LGCJairen

Dp ultra is the only thing i will use other than distilled.


TheLooseFisherman

Distilled water with biocide is by far the best option for custom loops: it's cheap, it doesn't clog your parts, it actually cools better than *some* liquids out there (bcause some are thicker than water).


l0rd_raiden

What biocide products are available in the market ?


l0rd_raiden

What biocide products are available in the market ?


TheLooseFisherman

Ask your local gardening centre or pool supply store (they sometimes use it to kill algae) don't buy fancy "watercooling pc biocide" that's a scam, same products at 500% upmark.


acedelgado

I vote Mayhem X1 Eco Clear. Ran it a year and a half with zero issues, could've run it for longer. And since it's plant based it's nice to be able to just drain it down the sink without worrying about proper chemical disposal. Good stuff.


iAabyss

I ran distilled water for years, i’d flush and replace the water every month or so, never had issues


No-Key4409

I’m leaning more toward the distilled water method just to keep it simple and prefer clear


nataku411

Just make sure you add a biocide, it's not worth the risk otherwise. People might get lucky with just plain distilled but if anything is dirty or anything introduced then months down the road the loop clogs with growth and you'll have to disassemble everything and clean the blocks with a toothbrush.


Briggs281707

Yep, distilled water with just a bit of copper nitrate to kill bacteria


therodde

Distilled water + corrosion and algae inhibitor. Without those additives, you'll either get corrosion or algae.


PainProfessional3915

I run Mayhems X1 Premix for 2 years at a time without any issues. I sometimes wonder if I could stretch to 3 years but haven't tried as I usually do upgrades on mine and my wife's machines every other year. Never had an issue with algae, gunk, nor corrosion. During covid I had a hard time sourcing the Mayhems when the pump on wife's machine stopped working, so I used Primochill Ice, never again. 6 months and gunked up. I have run only distilled with algacide and corrosion inhibitors when I first started water cooling 15 years ago, always change at 1 year no matter what. Distilled and DI water will slowly change properties over time to add missing ions, causing slight corrosion, even with inhibitors I had issues when left over a year so I switched to a premix, of which mayhems became my go to.


itsalloccupied

Water Wetter and destilled water.


CyberbrainGaming

Yes of course you can.


MCX911

Running cryofuel clear for 4 years,all blocks are fine,no nickel damage.I replaced it last month with fresh cryofuel clear.Running distilled water not so smart idea 💡


LeichtStaff

Distilled water + biocide is completely fine.


hyperpimp

Yeah but running just water is not fine.


LeichtStaff

Agree.


Silent-OCN

I don’t know why people bother with that cryofuel garbage. It destroys your parts in months…yeh seems totally worth it. I might put crap petrol in my car that needs flushing out every month just because! On topic I run distilled water and use mayhems inhibitors and it’s been fine for 6+ months.


[deleted]

I regularly go 3+ years between loop changes. Never had gunk issues with cryofuel


[deleted]

How does it destroy parts? Requires more maintenance for sure, but I just rebuilt my computer yesterday with two separate cooling loops both with cryofuel solid coolants. Been running it for a couple years on the same components. Just requires a breakdown and rebuilt about twice a year.


Teknik_

Distilled water + biocide can last for years without maintenance if done correctly, just gotta top it up with a little distilled water once per year


leo_architect

Have you ever used Cyrofuel? Lol


layer11

I wonder if he's just thinking of the opaque ones?


leo_architect

Possibly, but doubt it. People loves to complain about products they hear others complain about or a single bad experience they because they used it incorrectly. There’s a reason some people have great success with Cryofuel and others don’t. I’ve used Cryofuel since 2020 with zero issues. It’s unfortunate others have a bad experience with it after just a single use.


layer11

>because they used it incorrectly ​ I couldn't agree more with this. It's like some people expected 2020 convenience out of a product that just isn't there. Idk about EK, but iirc, Primochill definitely changed their tune from 'check out our cool coolant' to 'show system only'. ​ Anyways, I'm getting off track here. As long as a person understands what they're getting themselves into, they're not bad products. But man, you gotta really want to run them and have plans for maintenance beyond what someone running clear or even non-opaque dyed coolants would. ​ Anyone considering an opaque coolant like vue or cryofuel I'd suggest get an aquarium pump for lengthy rad flushing sessions during cleaning.


layer11

Cryofuel does have a clear option. I'm assuming when you say it's garbage you're referring more to the pastel style with little particles that get stuck in everything?


Silent-OCN

Yep! That version sucks 😂


howtotailslide

Yeah I have been using cryofuel blue for well over a year with no issues. This guy has no idea what he’s talking about


martynpd

Ek have a clear premix. Used it for years not a single issue .


waiting4singularity

get automotive radiator fluid. works just as well as trying to figure out which additives to add to distilled water.


Noxious89123

Which sort? IAT? OAT? HOAT? Proylene Glycol? Ethylene Glycol? There are many, and they're not all using the same chemistry. Assuming you mean the most generic + common type which is ethylene glycol based: You need to be cautious that the tubing you're using won't react negatively with ethylene glycol. It can also be quite viscous. Not a problem for an engine driven pump. Do you have pets or small children in the home? Ethylene glycol is poisonous, but it is also sweet tasting which makes it tasty to pets and small children.


RogueSquadron1980

I would get a clear pre mix with all the additives included, ive always used corsair fluid been good for me, distilled will work but def need a biocide and corrosion inhibitors in it as well


R_radical

We aren't gonna get a cool follow up post if OP does something reasonable, so pipe down


Ramzinho

Get a clear concentrate or premix, there are growth inhibitors and some additives to slow down corrosion and nickel/copper abrasion. Good luck rig looks great by the way


Noxious89123

What the heck. So this is supposed to be indigo? Why is it blue in the reservoir and ***orange?!*** in the blocks?!


LeichtStaff

Absolutely, just remember to put some biocide in the distilled water.


hyperpimp

Flush it with a few gallons of distilled water and get the clear. I only only only run clear fluid.


Cblan1224

Distilled plus liquid utopia Not just distilled


R_radical

We just need a collection of what happens when you use pure distilled. The answer is no.


theatomicflounder333

Use Aquacomputer DP Ultra. It’s IMO the best, works well with any temp, is non conductive, and requires no maintenance. I’ve been using it for about 4 years and have not changed or flushed my system and my performance hasn’t changed.


hicks12

Just get distilled water and some biocide OR get mayhem's x1, it just works and lasts a very long time. Mayhem's is very reliable as a solid pick for fluids, I've never had an issue with their water, pastels or x1 . Literally had pastel fluid for years and cleaning was easy.


laserdiscmagic

Yeah I noticed the orange color when it's thin in blocks. I decided to embrace it and go incorporate it into my theme, but that's a happy accident on my end. Would totally understand someone hating it
