2000 Haas VF0.
Been using Trim Microsol 585xt for a few months now with no issues. The other day I took out the coolant sump and cleaned chips out of it, and topped off my coolant (running a 9% solution). Ever since this maintenance, i'm getting really bad foaming with the coolant, and it overflows at the return to the chip tray. Any ideas what I screwed up here? Scratching my head on this one
Thanks yall
