CPR CR500 Wet/Dry Filter, Complete Package

The importance of the biological filter with marine aquaria has been acknowledged for years, particularly with fish-only systems that don’t rely on heavy amounts of live rock and live sand to provide biological filtration. The CPR CR series wet/dry filters replace inefficient undergravel systems and provide the most effective means of oxidizing toxic ammonia and nitrite by providing optimal growing conditions for large colonies of Nitrifying bacteria. Increased gas exchange and dissolved oxygen levels result as water flows in a thin layer over the filter media, our revolutionary Bio-BaleTM, which has the highest surface area of any filtration medium on the market today.

CPR CR500 Wet/Dry Filter, Complete Package. 


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.

* 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.
