Good point.

I use a sulphur denitrator in my system so this isn't really a concern. Water changes help all of this though... I also only use it occasionally... once you get levels where you want them always best to switch to a balanced additive system... (Ca+ Reactor, Kalk, 2 part, etc etc etc...) Also as someone else stated, Magnesium levels need to be right or you may never get your Calcium levels up...
