I'm starting up a high tech planted tank but going slow. I have a 3 bulb fixture (54 watts T5ho each bulb) over a 75 gallon tank with a 20 gallon sump. I won't be getting co2 for a few weeks, I'm just doing with excel right now. I have an amazon sword, anacharis, a moss ball, and some spiral val. The only one doing well is the moss ball. The other 3 aren't terrible but not great either, they're losing leaves slowly but surely. 54 watts plant-gro bulb for 4 hours on, 4 hours of, then 5 hours on, then off for the night. I turn thr other two 54 watt bulbs (10000k and 6500k) on for about 3 hours during the second daylight period. even the anacharis isn't doing great. Any ideas?
