how many watts for planted 25 gallon?
I have 25g planted tank. I want to take it up a notch and upgrade light from regular T5 to T5 HO. I have 2 choices:
1) 24in 48Watts, 2 bulbs, or
2) 20in 76Watts, 4 bulbs.
tank size is 24 long, 12 wide, 21 high
pressurized co2, dry fertilizers
Should I go with 48W or 76W?
