I have a 55 gallon planted tank with fish. After much research and reading, I now realize that I have too much light (Cora life: 4 65Watt 6700K lights), not enough plants and not dosing enough fertilzer for the type of tank I would like to maintain. I would like to use the Excel dosing method, and am able to use just two bulbs for 130 watts of lights, which from what I can gather from my research, this is still too much light. I do have the light raised 4 inches from the tank. My question is, will a film of tissue paper or some other substance help to bring down the intensity of my lighting?
