Aquatop Classic Aqua Flow CAF Sponge Filter

Description

For fresh and saltwater systems meet the CAF series sponge filters. Simple, economical and so easy to install, these offer excellent filtration while oxygenating the water. You simply can't beat the price and performance of the CAF Series which can be used as a stand-alone filter, a breeding filter or for extra biological filtration in heavily stocked aquariums. Even add it to your external or top filters as a pre-filtration unit! Another neat feature of the CAF Series is the airlift system for excellent biochemical filtration and pleasantly quiet operation. The foam materials support the colonization of bacteria, allowing for mechanical and biological filtration, which will break down harmful ammonia and nitrite. 

Features:

  • Excellent for breeders and hatcheries
  • Install with an Air Pump or Powerhead
  • Less maintenance than traditional filters
  • Easy and fast to clean
  • Economical and longer lasting
