That tank is 16 inches high, so a single T8 bulb gives about 15 micromols of PAR at the substrate, and it takes about 30 micromols for low light plants to do well. With your two bulbs you should have enough light - about 30 micromols. The color temperature of the bulbs is your personal choice - whatever makes the tank look like you want it to look. Most people don't use 12 hour photoperiods. That can lead to algae. Most of us, I think, use 8-10 hours.
Lighting a 20 Gallon Tall; thoughts??
Hey, I'm trying to get my first aquarium plants growing well and wanted to ask if my lighting set up makes sense. Any insight or suggestions would be great as I've only been in this hobby a couple months.
Tall 20 gallon with 8000K fluroescent and a 2300K Flora-glo fluorescent
(both 15W) 12 hours a day.
Plants include: anubias, water wisteria, amazon & argentine swords and umbrella plants
Does this sound like an appropriate lighting set up?? The whole watts and kelvins thing has me confused!! thanks a lot
