CPR

The value of a biological filter depends on how well it performs the tasks of oxygenation, ammonia conversion and gas exchange on a long term basis. In the wet/dry filter, air and water mix as water trickles over an exposed filter media such as Bio BaleTM. Biological filtration and gas exchange occur as the water flows in a thin layer over the media surface. (CR Series filters provide optimum growing conditions for bacteria which oxidize nitrite and toxic ammonia.) The rapid oxidation of ammonia and nitrite helps to maintain a stress free environment for aquatic life.

CPR filters are designed for long term reliability and ease of maintenance. These filters incorporate superior design features, such as:

  • Simple installation and operation.
  • Compact size to easily fit under your aquarium stand.
  • Excellent craftsmanship, all edges flame polished.
  • Efficient drip plate or drip lid dispersal.
  • Specially designed vented lids allow for proper gas exchange, and do not warp.

  • Dimensions (L x W x H): 16" x 8" x 12"

CPR Aquatic Aquarium Supplies
In Arcata, located in Northern California, the sea is a way of life. From the advanced Marine Biology department at Humboldt State University, just up the hill from CPR’s headquarters, to Humboldt Bay, about a mile west, CPR is nestled in a perfect environment to develop equipment for marine aquariums. CPR was started in a small garage in 1987 to produce biological filters for local aquarists. People who used CPR filters were impressed by the high quality and affordable prices. Word spread and the company grew. Since then, CPR has expanded to a 10,000 sq. ft. production facility and has developed many innovative products over the years. CPR is incorporating new ideas and technologies all the time. Their goal is to allow aquarists to place the highest performing products in their tanks at reasonable prices.
