Hello, \r\n\r\nI have a 28 gallon bow front aquarium with live rock, sand substrate, orange mushroom corals, pulsing Xenia corals, yellow wrasse, 2 clown fish and a small clean up crew. The size of the aquarium is 24" wide x 19" deep x 14" front to back. The equipment I have on the tank is a Sea Clone protein skimmer, Rena XP1 canister filter, 2 Hydor power heads, a Coralife power compact for my white lights and a Coralife 2 bulb T5 for my actinic lights. \r\n\r\nI would like to make more room on top of the tank and I am looking for a different light fixture. I am not sure if I should go with LED or a T5 light. Also, I am getting green hair algae on my power heads and I am not sure if that is from the lights or not. \r\n\r\nSince I am still rather new at this I am open to suggestions. \r\n\r\nThanks.
