I have a AquaRay GroBeam Ultima 1500 (attached spec).
I have the ability to dim these lights, is there a way of working how if any by how much i should dim these lights for an optimum balance of light vs plant/algae growth?
My tank is a 155L cube.
So I recently set up a 20 gallon long tank, which as been a work in progress. I'm at the point where I need lighting for the tank. I want to make sure it's something I'm going to be really happy with, because it will have low-high light requiring plants in it.
I current just bought T-2 lighting...
