View Full Version : Tunze Calcium reactor media

Hi All,

Is anyone using the Tunze Calcium carbonate?

I have a deltec pf501 reactor and have been using rowalith c+ which is OK but near the end of the media it always clogs and kills my pump.

I use to have a korallin using it with ARM coarse media which was great. ARM literally costs an arm and a leg here in europe (35euros a box, like $14USD from marinedepot). Tunze calcium carbonate is very cheap 18euros for 1.3 gallons.

Anyone have experience with this stuff? Melting point and so on. Can it be used with a magnesium chips?
