If I got a small filter instead, could I remove the airpump and the underground filter think the airpump sits in and just use the filter?
Those of you that do use the filters, how often and how much are you changing your tanks?
I like under gravel filters so I would keep it.
For tanks under 5 gallons you'll have to do weekly water changes and anythin larger can be put on a monthly schedule.
