Undergravel filters are usually always considered unreliable as all they really do is pull the waste productis further down into the very place you are trying to remove it from. They do a poor job and cause a lot of hassle. There have been cases on this forum where tanks have had to be rescued from very badly kept or handled undergravel filters and they are very difficult to maintain. I would jettison the idea of an undergravel filter and get a Power Filter big enough to handle the tank and let thst be enough.Joe G said:I have a 10-Gallon Tank it came with a compatible Power filter.
I and I am undecided if I should also get a, Undergravel Filter, or would that be too much.
