I have a 55g with crushed coral, one 48" double bulb strip, has white and blue atinic.emperor 280, cpr bak-pak 2. need to purchase a powerhead and heaters. I just bought the tank used.The tank is sitting empty right know. Have had tanks in the past but little sucess. I will be buying ro system.The tanks i had in the past had algae problems. I think was due to not using ro water. Would like to start out slow and do this one right. want to start with some live rock and anemones and clownfish. do i need to upgrade my lighting for my anemones or is the higher powered lights just for corals? would like to turn into reef system down the road but want to start slow and add things needed to tank over time. Please help.
