Re: anchor brand coolant review?
The green or orange automotive stuff is poison, ethylene glycol, where the others are most likely propylene glycol and non-toxic.
I have always used RV anti-freeze used for winterizing RV and boats, a pink color. Most likely the cheapest, has worked fine for me, no additives at all to lubricate pumps or algacide but the procon pumps in the coolers I have had are designed to last for years pumping tap water so I don't think that is that important to have a lubricant. If you get a leak or change the coolant it isn't hazardous waste with propylene glycol so that is a plus, just my 2 cents. MSDS would be key to know for sure.
