Might be a lot of effort and after reading Anthony's post, wondering if was necessary, but when I picked up a clam and frogspawn that was kept under 2x150W for years and placed in my tank (2x250W) placed piece of light diffuser (eggcrating) on top of the tank and over the new additions. On the diffuser did something like 15 panels of window screen and removed one every day or two.
