2 36" fixtures over a 125 72" tank, 148" fixture over a 40long, 136" fixture each over 2 40B, and 1 36" fixture over a 30 long. All tanks are high tech. Co2
injected, and PPS pro fert regimen.
The crazy thing is, on the 40 long, after the HO
light went out, I put a twin tube NO T-8 fixture, and a T-5 NO twin tube fixture on the tank, and the plants are doing excellent. I believe the bulbs in the Oddysea fixture were not very good, even though they were only a few months old.
Guess there is something to be said for the old T-8 bulbs. Just tough to get enough of them over a tank.!!
