Hi Ja,

I'd only suggest you change the crushed coral for some sugar fine aragonite. It would be far better.

Okay. thanks

Why would it be better?

Crushed Coral can catch little bits of food and junk which rots and causes massive nitrates.

That skimmer seems undersized. Most go with one rated at least 150% of their tank capacity.

Also, in addition to what Amber said, the large particles in CC are too heavy for the microbes in the bed to move about. This makes for a stagnant bed that can go from anoxic to fully anaerobic. A situation that can produce unwanted byproducts.
