Which setup would be better for a 29 gallon tall? Or what filter setup would be best? Would like a canister filter for it but don't really have the money to spend for one of those right now. I have an air pump right now that isn't being used for anything could I use that for a sponge filter in a plants tank?
Powerhead in my view would be better with sponge filter in planted tank.
With air pump,CO2 produced by fishes and bacterial activity would be lost at the surface .
So long as fishes weren't being swept around the tank,I would perhaps leave things as they are.
Plant's moving about would to me,,,indicate good circulation.
You could try moving the Aquaclear closer to the middle of the tank as opposed to one side and see if this doesn't help.
When I first set up canister,I placed the return (spraybar) on one end of the tank and plant's all leaned in one direction. I then moved the spray bar to the middle of the tank, and plant's all stand straight but they all move slightly which in my mind, is a good thing. It ensures nutrient's are distributed through out the tank and fish waste, which also provides nutrient's for plant's, doesn't all gather in one area.Hope this helps.
