Aqua Computer Double Protect Ultra 1 L

This stuff is top notch. Comes with biocides already mixed in the coolant. Does not damage or corrode nickel plated water blocks, unlike some others. There’s really no reason to buy anything else if you want clear coolant. Doesn’t get any better for the price in my opinion.

It is doing its job. I replaced some other brand that was purple that had degraded and was not doing its job. This is working great so far.

I've bought this fluid a few times in the past year. It has performed quite well. Unfortuantely, I've had bad luck with the other parts in my system requiring a complete dismantle of the loop to reach those parts needing replacement and thus requiring replacement of the fluid. So far I'm happy with the fluid. The other parts of the computer... not so much. However, the last batch I just got was delivered with the cap broken and the fluid was leaking everywhere before I even opened the packaging. Unfortunate.

So the coolant is legitimately clear with no tinge to it. I recommend this or koolance 702 for all your pc coolant needs, they are by far the best that i know of. The company modmymods who sells/carries this in the USA makes their own "modwater" too which ive heard pretty good things about and have personally used their ultra pure modwater to mix with a concentrate with great results.

I upgraded from corsair coolant and this left a small film at the top of my reservoir. I bought this because I was told on reddit it is the best coolant for your pc, as well as the low conductivity. It seems to be a decent coolant, but I am not sure how this weird film appeared at the top.

Cancelled order, a week past, and the product was shipped regardless, returning results in return shipping fee, and restocking fees. It's obvious this company doesn't need customers.

Works as expected

One of connectors broke while under load and this fluid sprayed all over the internals of my computer. The sound cart got the worst of and died on the spot, but nothing else was damaged despite being wet. Also, while I was waiting for my components to dry out so I could see what the damage was, I discovered that this fluid doesn't evaporate the way distilled water would have so I had to use paper towels to collect as much as I could. Since it doesn't evaporate as readily, I won't have to worry about adding fluid to my loop for a while.
