It's going great - but the test did chance a little bit. I had too many barred midas babies, so the dad went back in the 300 and the mom in a 75 w/ her babies. It turned the 135 into a low tech planted tank (anubias and java fern & moss) w/ a bunch of smaller/mid fish. I've only done water changes (no other cleaning) and it has worked great. You can see in the pics (just took and haven't done a water change in a week) that the super-lifters create a ton of water movement. It blows the fish around on the other end of the tank (I only have on one end of a 6 ft tank), and this is now all run on just one 26 watt air pump - and it is much quieter than normal sponge filters. BTW, I put one on a heavily stocked native 10 gallon tank my son has, and it is doing really well too.
