What kinds of materials or maintenance is required to maintain 50 gallons of coolant over long periods?
What additives or "pellets" are worth the money?
I use kool mist which I love but after a few months I get the floaty oily scum on the surface and also these snot-like deposits that clog the inlet screen. It also seems like i am constantly having to add water and adjust the concentration, is this normal evaporation?
Anyone have experience with additives?
Also would an aerator or circulator pump help?
What about an external tank to periodically cycle and filter the tank coolant?
Any help is appreciated.
Access to the minimill sump is pretty cramped so it is a real hassle to fix any coolant problem when it happens. The roll-out style was much easier to maintain.
