I set this up about three weeks ago, and it's working great. I have two angels and a pleco in it, doing great and growing. It's my ghetto grow tank and light reflector. My turtles leave my original fish alone, but if I put a new small fish in their aquarium they chase it around and eat it. I decided to set this grow tank up so I can let new fish get big enough to add to the turtle tank. I'm getting a 125 gallon aquarium for the turtles soon, so if they still want to chase the angels I will move the fish back into the 40 gal.
I had the large Critter keeper and some of the PVC pieces, so I only had to spend about $5 for the ball valve and a few connectors. The reflector is a $2 sheet of aluminum that I cut, bent and bolted into a reflector, and added a $2 bulb base and $1 extension cord.
I used the pump for the filter to pump water into the intake for the Critter Keeper, with a ball valve to control the flow or shut it off for maintenance. The main output drains down through the filter in the main tank. Then I added a backup drain, so if I get a clog in the filter or a twist in the drain line the water will still drain back into the main tank, instead of over flowing 40 gallons of water onto the floor.
