my 20g reef (need evaluation)

[reef4life]

Hello, I have a 20g reef which is about 7months old. It consists of
30lb live fiji rock
30lbs live sand
flame angel
2 clowns
colt coral
2 carnations
polyps
mushrooms
55w pc
304fluval
prizm skimmer
hagen 302 powerhead

plans- adding another 55w and a fan on the canopy. And then, buys some corals, and buy some more coral, then some more.


So, I want the pros evalution on my tank. I want to ask you guys if I am doing things right. I feed lil variety of frozen food daily. For my corals, I give KENT MARINE CORAL_VITE, its supposed to have everything in it so I put in 2ml every week. And twice a week, I put in a pump of BIO-PLANKTON. I do water changes every two weeks. Water cond. is fine, corals are well, ph is at 8.0-8.1
My concern is if I am putting in the right stuff for the corals...
