If you are planning on keeping SPS or clams then I would definately keep it.
Anyone with alot of SPS have any good info for me? The problem I see is that kalk can only maintain levels, not raise them. Once you have high calcium demand kalk can not even maintain levels without help from ca additives. With that said, what would be the point of even using kalk. Only answers I can come up with is slightly lower ca additive costs and to help with higher pH. But once you reach a high ca demand in your tank, if you use alot of kalk it then lowers you mag. So it is no longer cheaper on ca additives if you now have to add more mag additive. So on a high ca demand tank the only benefit I can see is for pH.
