Hello all, I finally got my canopy together. Its not all trimmed out yet, but the lights are mounted and working. My question is where do I mount my ballast? The most convenient place would be underneath the lid with the lights, would this be a bad idea? If I did mount them there what would be the downsides to this location? I do plan to add fans to this setup later on, but for now this is what I have. Also I have 2=55watt PC's, and 2=18watt T-5's and for those who don't know they are on a 20 gallon long. With the new canopy they sit about 7-8 inches above the surface of the water is this to high off the top of the water? All comments, and suggestions are welcome. Thanks all, and God bless.
