alright so i have a 175 watt mh and 4 65 watt powercompacts over my 92 corner. I am thinking of upgrading to a 250 watt mh, and switching the powercompacts for t5 lighting. I am curious as to where i can find 36inch t5 retros, and which ones would be the ebst to go for. I keep softies, lps, clams, and sps right now and was wondering if going with the 250 and t5's might be overkill. I'm still not sure how many t5s i should go with either. All i know is i got the nova extreme t5 fixture with 4 24 watt t5's and its much brighter then my old csl 2X65 watt pc fixture for my 25 gallon tank so i'm thinking of changing the lights out on my 92. Perhaps just changing the power compacts to t5's would give me enough of a boost that i dont need to change the mh? i'm getting great growth with the t5's on the 25, but i can't live without the sparkle and pop from mh. Any suggestions?
