all coral doing ok... I took reactor off line for moment. so as I tinkered with stuff as I've been doing I figured why I went theough a few 3 gallons in two days. I had been adjusting flow in sump turning ball valves and also messing with skimmer so this caused the sump level
to drop. to add to it I messed with both my reactors also so topping off reactors with water caused water level fluctuations again more Kalk top off... I'll just top off fresh for 3 days then test
