You have the Aquaticlife light? That's what I have over my 20H, but I swapped out both bulbs for ones that are 14W 6700K.
Yup that's the one i have. I wish my LFS sold 14W 6700k. They only appear to sell 24 inch 24 w bulbs. They have 6000k, 10000k and rosettas. Might have to go online or something.
