On my 100 gallon aquarium, I run two Coralife 4x65/55 watt bulbs. It keeps the water very hot. When summer comes, my apartment gets ridiculously hot! So my question is...what is the best kind of fixture to use to keep the heat down?
But I also need the fixture to give me a decent amount of light at the substrate. I want to be able to grow glosso and such.
