ok guys got a 6x2x2 and it is cycling as we speak. i have a sump which is running a 6000lph return, 3 drilled holes 40mm2 each.5 2000lph power heads, 2 with filters (the aqua one 104 maxi jet) and 2 660 lph power heads for surface areation. i have a 8 bank of t5's.i dont think this is enough light to support hard corals even if there at the very top 7 inches from the source. i was thinking of buying a 3x 250W MH with 2 t5's on the side with 4 moon lights only 470 on ebay.just wondering if its necessary or not? they r double ended aswell and its a very good bargin im thinking but 250W x 3 + 2 T5's about 6 foot long would eat electricity like a monster.its a nice upgrade.about 17000 lph turn over at 700 litres so about 23 turns an hour,skimmer and refugium in the sump with cheato and a 3 foot fluro over the refugium in reverse cycle. 80kg's of live rock. blue tang, powder blue tang, yellow tang, lipstick tang, clown trigger, pocasso trigger, clown, blenny, 8 green chromos,3 yellow chromos and my pride and joy purple tang. is this an ok setup for a reef tank?(i know the triggers arent to reef safe)..... PS hoping to get 6 more green chromos and maybe a nigga trigger. i wont be able to have ANY small crustations but im going to experiment because my triggers have never eaten large shrimp as feeders b4 only mysis! please i need feed back!!!!!!!!! ta
