Lighting for a 30+ gallon tank?
What kind of lighting should I use?
I have a ~34 gallon tank. It is a 30 "tall" tank, so it is 24 inches wide
under the hood. Currently, it is lit by 2 20watt fluorescent
"grow/aquarium" tubes. I have cylinder co2 injection at ~22.
I have mostly lower light plants now:
Pigmy "chain" sword
I also have 3 discus and 15 or so cardinal tetras.
My plants seem to be doing OK, but the algae is over competing them. I
think this may be due to a lack of lighting. What does this group recommend
for a tank this size? I don't want to blind my discus, and everything must
fit in the 24 inch hood.
