Double Sponge Filter for Aquarium with Spares

Quick & Easy Specs

Multi-Filtration Functions This sponge aquarium filter combines bio-filtration, oxygenation, and physical filtration in one. It also creates a gentle water flow to maintain excellent water quality. This ensures your small fish or shrimp can live a happy and healthy life.

Filter Dimensions The small filter measures 6" in width and 9"-13" in height, with a sponge inner circle diameter of 0.39 inches. It is suitable for 10 to 40 gallon fish tanks. The medium filter, measuring 6.3" in width and 9"-13" in height, has a sponge inner circle diameter of 0.59 inches, recommended for tanks from 15 to 55 gallons. For larger tanks, using two filters is suggested.

Package Includes The package includes two double sponge filters with holding containers, one bag of ceramic media balls, and two pairs of sponges. Please note, this filter must be used with an air pump and a standard 4mm air hose, which are not included. For best results, choose a powerful enough air pump based on your fish tank size.

Detachable Fine Sponges The 2 fine sponges are easy to detach and clean or replace. They have a fine pore size of 60ppi, providing more surface area for beneficial bacteria to thrive. Avoid using tap water to clean them; instead, rinse or squeeze them with aquarium water.

Easy to Use All parts are easily detachable, allowing for simple assembly. The filter comes with 2 strong suction cups, ensuring it stays securely in place underwater without floating. The water outlet tube is extendable and rotatable, allowing you to adjust the outlet position above or below the waterline.
