This build is a bit of an early Xmas present for The_fishy. I got some input from her on the design and this is the product as it sits today. Right now 3 of the 4 10 gallon tanks are running. The stand itself is 2x4 which has been stained and had a generous coat of polyurethane applied by The_fishy. All of the tanks are ran on the 29 gallon DYI sump. For mechanical filtration we are getting some sponges for a fluval FX filter to fit in a 6inch piece of pipe. Right now the bioballs are being weighed down by some plant pots which will be removed later. The pump leads to a manifold with 5/16 inch adjustable valves. I had to remove the built in check valve out of each valve to help improve flow. The 1/2 inch overflow does not allow for the valves to be fully open so I am upgrading to 3/4 inch. For now the system can run with the valves opened about 1/3 of the way. If anyone has any questions about or ideas to improve the build please comment!!!
