Top Fin Sponge Filter

The Top Fin SF20 Sponge Filter provides mechanical and biological filtration to help keep water clear and your tank healthy. Unlike standard filters, a sponge filter is fish-safe because it doesn’t have any moving parts, protecting smaller fish from entrapment or harm. Only at PetSmart.

Instructions: Read all instructions included inside the packaging before use. Advice for Use: Replace sponge filter once per month. 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.
