Change out 25-30% of the water weekly. Use a water conditioner and bacteria supplement (sold separately) every time you add fresh tap water to your aquarium. The air stone should be connected with airline tubing and air pump (tubing and pump sold separately). If using this filter as a supplement, do not replace sponge filter and filter cartridge media in your primary filter on the same day, as this will greatly disturb the build-up of beneficial bacteria in your tank.
