I have a fluval 306 running on it, seems to work well enough. I did have quite a few fish in there at one point without problems.
My plan with this is to keep the stock pretty low so that should be over filtered. Prob going to put 20 or so neons, green neons if I can find some. I know one shop nearby has them from time to time, the question is can I wait... Anyways those and once the shrimp population gets big enough I'm going to bring a bolivian ram from another tank that's getting picked on a bit. Give it the penthouse to itself, complete with culled shrimp buffet.
