NO BUGS
I put an aquarium bubbler in the coolant tank on my crankshaft grinder to keep the coolant moving. This keeps the algae from blooming and keeps the coolant better to work with. I used a pair of old main caps wired to the base to form a stand. When I don’t grind for a week or more it really helps keep the coolant clear.
