Hi,

Hmmm..pH should drop a bit when the kalk reactor is removed. Kalk adds OH- (basically increases pH) and Ca++. Anyway, I think that affects the skimmer.

Ca reactors drop pH...so it also should have moved in the same direction (down). Hmmm...maybe its the alk...not sure why your pH isn't dropping. How are you measuring pH ?

Coraline...I think your reef is reacting to your sudden shift between kalk and reactor...maybe it just needs more time.

Say...have you bought actinics from Albrite before ? I was quoted a $13 a piece for a 4'.
