Hello, I currently am running an undergravel filter in a 25 gallon tall (Lightly planted anubias and java fern and I have 11 assorted small fish, molly, platys, tetras, etc. and 3 amano shrimp. I want to turn down the flow on my UGF powerhead and add a sponge filter to the other side on the tank using an airstone. My reason for this is that I set up the tank a 4 months ago and I have read that UGFs can be bad long term. I don't want to remove the entire UGF set up and mess up the tank, but want to maybe add a sponge filter ALSO in the tank and turn down the flow in the UGF low so its only being used a little bit. OR, is it possible to leave the UGF plates and remove the tube and powerhead without causing issues later? I am just trying to get ideas from this community on what other people have done. Any thoughts or help would be appreciated.
