So my 60L cube tank currently runs a DIY filter. I was getting mulm buildup quite regularly on the substrate at the back of the tank, mainly from the driftwood. My filter has done a decent job sorting it out. Recently however I'm cleaning the sponge almost every couple of days, and if left for too long, the outflow is almost minimal. I think a solution would be something that gets water movement at both the substrate level and the midwater level. After looking, the only thing I can find is the Fluval Hagen U3 & U4. A bit on the pricier side for me, but I think it could be a good investment in this tank. (External filters won't fit this tank)
What sort of experience have other members had with these filters? Good with small fish? Neocaridina shrimp? snails?
TIA
