What fun! Setting up a new tank. All of the possibilities. Have fun with all that. While you are working on things, you might want to consider cutting out a rectangle out of the rear of the canopy. Leave four or six inches on each corner and open up the back. You will get a lot more air in there and you can mount those computer fans to blow over the T5s and over the water surface. If you have a chiller, you may certainly disregard this suggestion. HA
