Thought I would post some more pics. This kinda shows my water change solution. I just went to Home Depot and bought some small elbows, a small ball valve, some tubing and a screw-in quick connect pieces. So I measured everything, glued all the pieces together and painted it black, minus the hose going into the tank. Then I had to fit it in chamber #1 and have my hood open and close. So I had to Dremel a notch in the back for the pipe to route through. As you can see in the pic on the right: (You can also see the ATO tube with the micro irrigation elbow I talked about earlier, more toward the left.)

Then I just secured everything to the back with some stick-on mounts and zip ties. I bought a small Hydor pico pump for the bottom of the tube going into chamber #1 to pump out water (the filter plate in chamber 1 was already removed). So I hooked up the hydor pump to one of my switches and have another small pump with a little more power hooked up to another switch. I made another short piece of hose with the other end of the screw-in quick connect that hooks up to the other pump in a bucket. So when I do a water change I just have 2 marked buckets, one for water in and one for water out. I can pump both ways through one pipe with the pumps on each end with no issues. No more siphoning and much quicker!
