I have a 55g fish only tank with live sand and about 20lbs of live rock(for show). I just purchased a lighting timer(daylight, acentic, lunar) and wanted to know if anyone had any suggestions on how many hours I should run each light for optimal results. I have a 265w compact light with lunar lights. I started to develop algae on the glass and live rock. The tank has been running for approximately 6-8 months. Live stock: Yellow tang, atlantic blue tang, powder brown tang, 2 clowns, porcupine puffer, spotted sweetlips, and purple antheia.
