I was skeptical about getting this in the beginning. But if we don''t take risks we don''t know. So I bought, and used it for the first time in a new build that consists of dual pumps, and dual radiators. 4 years later there is absolutely ZERO problems with the loop. The water is as clear as it was when I put it in there. Zero growth, and zero smell. Throughout my 13, or so years building water cooled computers I''ve use a couple dozen products from every retailer you can think of. Dead water is the only product I will use from this point forward. On a side not. I have absolutely no idea why my display name is "Disappointed"....

Been running this in my home server for almost 2 years now with Koolance UV Red fluid and soft tubing. 2 Drops every 6 months on the dot. It''s cheap, it''s easy, and it works. What more can you ask for?

It''s copper sulfate, which has been used for centuries as a fungicide, pesticide, herbicide, and various other applications. I get a lot of these for free, or nearly free, when buying kits from FrozenCPU and other sites. There seems to be a surge (based on my clients'' specifications) in custom water-cooled builds in the last couple of years. These drops have performed great when used in conjunction with a pure copper or silver coil/plug/coin (yeah, I had a somewhat weird customer that used a 1 troy ounce American Silver Eagle coin in his loop). Use these two with a cheap solution of distilled water with 2.5% to 4% hy-per-lube super coolant(go to an automotive parts store) and you will only need to flush out the system every 2 years. BTW, 2.5% coolant to 97.5% distilled is a 1:39 ratio (4% coolant to 96% distilled is 1:24). Just don''t go overboard on the coolant or you will have dezincification if you have any brass in your loop. However, I am digressing. These are great with 100% distilled water loops or used in combination with other substances.
