The best way to add calcium

[Doug]

I agree with Brad. Its easy to maintain calcium levels with kalk, but hard to raise them. Its funny Kent said that, as their Turbo calcium is reported to be one of the best products to raise low calcium levels. I do agree on kalk being the best of all for calcium maint.

I find B-Ionic or C-Balance, to be incredible coralline algae growers.

As I still drip mine, {into a 225 gal, , I also was wondering how the float switches hold up.
