alk being too high. Do test your water.
ok so these are my readings
CA - 460
MG - 1500
ALK - tested on my hanna checker got a 4.7 then tested with my salifert got a 7.0 so iam gonna go with the 7.0
one thing is when i do dose alk i pour it right into my vortech which the sps is right in front of but i havent dosed in over a week but maybe that can be it???
also just changed my bulbs last sunday
Could be that. I would try lowering CA, and MG. When Ca is high it can also cause problems.
I see, I guess you dont have a sump else you can dose in there instead. Try dosing smaller amount of alk but more frequent instead of one shot. Goodluck.
