such a sweetheart. now you understand sanhish. i think 3x250 would be better with your 4 t-5. just my preference 2x250 i dont think its enough. but its your reef tank
Although it can be difficult to decipher Sahn's posts... he is saying that even with 2x 250w mh's, you will not have a lot of light penetrating to the bottom of a 30" tall tank so you May want to think about 400w mh's or keep only very low light corals at the bottom of your tank. 175w would not be enough IMO
