I just finished my DIY ATO for my 24 aquapod.
here is what I did.
Supplies
Float switch. Ebay ( $0.10 + $2.87 shipping )
Battery air pump. Walmart $6.97
2 liter bottle
Rigid airline
airline
1.5" Acrylic strip
First I built a bracket to hold the switch by melting and bending the acrylic to make a bracket.
Then I took the airpump and cut the wire from the battery to the moter and then connected the switch. Then I drilled a hole in the back of the pump for the wires.
After I installed the switch in the tank and adjusted it to my desired water level, I drilled two holes in the top of the two liter bottle cap one for the airline and one for the rigid water line.
Then I filled the two liter with water and connected the air pump to the bottle, and added the water return line to my tank. In a test the air pump drained the entire two liters in 4.5 min which is about 14 GPH. It works great and was less than $15 to make!
