just finished (ok, maybe not "just" finished... but you get the idea. lol) building a low flow wet/dry sump for bio filtration for one of my exodon tanks.
standard pvc overflow. (first time making one. usually i just buy the box)
painted and cured
some of the other pipes and valves
first test (check valve still wasn't installed at this point. also, there is no filter in the sump, its just the bucket)
check valved installed and second test running. (pipes behind the tank where they belong, and bio tower installed)
looks like the flow is still a little too low to keep the overflow primed without cavitation. but i dont want to go much bigger. hopefully i can get a hold of a couple of slightly larger pumps to see the bare minimum i can get away with.
