Box filter with filter sponge and pumice stone - mini

Efficient Box Filter with Sponge and Pumice Stone

• This box filter is ideal for maintaining a healthy bacterial culture in your aquarium.
  The sponge provides both biological and mechanical filtration, capturing fine particles in the water to keep it crystal clear.
• The pumice stone has a porous structure that offers a large surface area for beneficial bacteria to grow.
• The filter is connected to an air pump, which creates water flow through the filter media and sponge while aerating the water through the air stone.

Note: Air pump and airline tubing are required (not included).
