| Im running Hamilton 20k But just one (typo at the top), at this time because of heat. I live in an area that gets 105 degrees plus in the summer.I dont want to use a chiller if I can get away with it. Im only 19.5 inches deep in this tank so if I find it isnt enough light (comes out to 11 watts per gallon with pcs) I will go with 1- 400 halide with 20k xm bulb.so I dont have the heat of 2 bulbs, but we will see how it goes.Im going to try to get some close up this weekend. |
