Fluval Clearmax filter media

[.Newman.]

OK I was looking for some Phosphate removing media and stumbled upon this. Has anyone on here used it in their tank with coral? how did that go?

 

EDIT: nevermind guys, if anyone has this same question, here is the answer:

DO NOT use clearmax with reef tanks because it will irritate sessile inverts, including all corals.

It is perfect for Fish-Only tanks only.

 

I'm better off using regular FerricOxide stuff.
