Calcium Level

[sandy]

What should my calcium level be in a FOWLR. I want the good growth to continue on my rocks.
It was 500. I stopped adding the B-Ionic because I heard it should be around 400. It is at 375. Add calcium or not?

Add it.. You want to keep it somewhere around 450 or so. Coraline really uses calcium up. Make sure your Alk levels are also in check. Keeping these 2 right will help with your coraline and also help keep unwanted algea from growing..

You may also want to keep the calcium levels up for the health of your crabs, snails, and shrimps that require calcium to grow and molt.
