A few months ago I bought a 48" fugeray2 for my 75 which has pressurized CO2. But after a few months I noticed some growth but not as much as when I had my 3 bulb T5HO. Also I've noticed a bit more algae than I like and my red plants have begun to fade. The fugeray seemed more like an accent fixture due to it being so thin. So this morning I threw on my 2 bulb T5HO to go along with my LED. I have it timed where both fixtures are on at the same time for only 4 hours a day. Is this too much? Too little? Or just right?
