i have mh lights 785 watts still in package, no corals as of yet except brown mushrooms, 150 gal. i am in hospital right now doin chemo i will be here till sat. if memory is right it is 27 in. deep as of now i have 2700 gph i am thinking i need to get that up to 3500-4000, i want easy corals to start with, it seems most of the cool looking corals can take-over a tank i don't want thati'm pretty sure i don't want anything over 6-8 in. so i can have more color/variety as my expierience develops any advice?
