Phosphate problem/solution

[molybdenumman]

I seem to be having some phosphate problems in my tank. Levels up near 2.5 ppm. I have some Kent phosphate sponge but am leary to try it. In the past, I tried using a different brand of phosphate remover which resulting in the destruction of my leather coral.

I have several soft corals in my 55g tank right now, and I am wondering if anyone can give me some advise on the phosphate sponge from Kent?

Thanks
