thanks everyone, well it is a 40 gallon breeder thank with my own DIY stand and hood i run a quad T5 light system, that i am in the process of upgrading the bulbs to ATI's so far i have switched out 2 and what a difference. i am running, 1 ture actinic, 1 purple plus, 1 coral +, and a Blue +. I only wish i would have ran these lights sooner i highly recommend them, they are a little $$$$$ but well worth the money, also i have a Odyssea PS160 Protein Skimmer, and a Odyssea CFS 500 Canister Filter my tank has been running for about 1year now (look for more posts on this forum titled MY REEF TANK i will post more pics soon)
