So I have no corals yet but will be adding. I have 2 clowns, 1 goby, 1 midas blenny and will be adding more fish. I have 2 32 hydra hds and wondering if I should get diffusers or shades? I want to get rid of the light spill. However im wondering if my lights are too powerful for my 75gall ext. Whenever they come on my clowns go from where they always stay at the top of tank to the middle or some shaded area. Does that mean the light is too strong? Which means I should do diffusers? If up to me all i care is getting rid of light spill and making my light work efficiently and properly once corals are in...
