Hi, Im going to be refilling my w/c loop soon. I have been using swiftech hydrx, but I have read too much about it clogging up the loop after a while so im not going to use it again. The parts included in my loop are in my sig, do I need any corrosion protection? (afaik its all copper but Im not 100% sure) And If I need corrosion protection what is the best coolant to use, and do I need biocide also? And if not is antifreeze + distilled water + dye the best thing to use or do I need biocide also?
