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 Bale™. 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
Precision craftsmanship, all edges flame polished
Efficient drip plate or drip lid dispersal
Specially designed vented lids allow for proper gas exchange, and does not warp

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 us, to Humboldt Bay, about a mile west, we`re fortunate to be 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 we grew. Since then, we have expanded to a 10,000 sq. ft. production facility and have developed the innovative product line you see here. We`re adding new ideas all the time. Our basic goal is to allow you to put the highest performing systems in your hands at reasonable prices.
