Hi guys. Bit of a quandary. I’ve come into possession of a very nice EK 250mm res, and I’m thinking of using it instead of the XSPC bay res I have. I can mount it in the front section of my Yeong Yang, and have it on show. The overall theme of my case is blue, with black tubing, but I’d love to have a Res containing a UV reactive premix in there too. My concern though is that premixes are a lot less durable and prone to gunking up and breaking down over time. I don’t really want to be dissembling my rig every month to clean the clogged blocks! Tomshardwares guide to watercooling has this to say: “Also, this is a wise time to consider additives for your water. Almost all seasoned watercooling veterans will tell you to use only distilled water and either a biocide (such as PTNuke or similar) or a KillCoil...or both. A killcoil is a coil of .9999 pure silver that you drop into your reservoir to inhibit growth of algae and other critters. Most will highly advise against using premixes; some of these even precipitate out and can clog your blocks.” What do we all think about this? Is it not worth the hassle, or have premixed dyes matured to a level where they are almost on par with distilled water?
