First coral, what kind of care?
 

I have started a 15 - 20 gallon reef tank. I took the LR, Sand and water from my larger tank.

I have a chunk of colt in there and plan on adding more.

what do you suggest I supplement feed my corals with?

Are there any specific additives I need to worry about when doing water changes?

Also, I have 65 watts of PC lighting. The tank is 1 foot deep. What sort of lighting would be required if I wanted to get an anemone or a clam?

To keep nitrates in check, I will be avoiding fish for now. I plan on keeping just corals and other inverts and keep the fish for my FOLR tank.

I have a coral banded shrimp in there right now.
