So, I have a 10 gallon Perfecto Kit tank (20x10x12, canopy, and incandescent fixture) that I fitted with two spiral (or twisty) 26w CFLs. I have pressurized CO2 running on it as well.
The problem is that, 1) the spiral design is flawed or inefficient and the largest "U" shaped CFL (the longer, narrower ones) comes in at only 20w a piece. 2) The spirals are short and stubby so there is far less light in certain areas of the tank (middle, front, and far edges) because of where the bulbs are situated in the ballast that sits on the kit's canopy.
Now, at the LFS, there is a 20" ballast with two 18w T5HO bulbs. I was wondering if two 18w T5HO bulbs that reached across the entire tank would be better then the two 26w spirals.
Input is much appreciated.
