Hydro Sponge 2 Aquarium Filter

In addition, the Hydro-Sponge traps larger waste particles, mechanically cleaning the water without trapping the baby fish.

Five Sizes Available:

  • - Hydro Sponge I, up to 10 gal.
  • - Hydro Sponge II, up to 20 gal.
  • - Hydro Sponge III, up to 30 gal.
  • - Hydro Sponge IV, up to 80 gal.
  • - Hydro Sponge V, up to 120 gal.

  1. Great sponge filter design, great price: Review by Rascowo
    Product Rating:

    Aquacave is a great resource and good value. Prices are competitive and shipping is quick. The Hydro Sponge II sponge filter is the best design of all the sponge filters out there as far as I am concerned. This is an excellent design for a sponge filter. The core is designed so that you can add on extra core tubes and build up from the gravel. This is great if you want to add an additional sponge because you can use a smaller diameter sponge and go up instead of using the larger size you may need but do not want to take up a wider diameter of your corner with the larger sponges. The core also designed so that you can even place a few ceramic bio-rings into the core. The base is weighted sufficiently to hold down the filter. (Posted on 2/1/2017)
