I bought a tank from a friend with the rock and coral still in it. I romoved all the sps and the most of the lps leaving only the zoas and palys and acouple of trumpets. The live stock currently is only a starie eyed blenny and a dragonface pipe fish. I added dragonsbreath and a seawhip for hitching and intend to add more hitches in the future. I do have a sand bed but i put alot of clean up crew in to help with any detritus that may acumilate. I have been able to maintain a temp of 70-72°. The tank has a sump and an oversized skimmer. I have been doing 10% water changes weekly. My plan is to add a pair of male H. Erectus. I have acouple questions. Are the trumpets ok or do they need to go? Should i add more algea to the sand bed and if so which ones?
