I have a 30 gal tank that has been operating fine for about 4 years. Very healthy with only a few deaths from sickness in the odd individual fish. Never had any outbreaks or Algae problems. My tank is heavily planted and has a small co2 unit.
Question is how many sponges do you use, what type of carbon insert or combo, how often do you change them, what are the main bebefits of the different types of insert.
I have been changing the carbon about once a month and the sponges about once every 3 months.... seems to work well but curious on other approaches.
