CPR CR3000 Wet-Dry Filter Information

Product Manuals & Documentation

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.
  • Separate sump unit (20 gal.) included.
  • Recommended Tank Size: Up to 400 Gallons
  • Media Capacity: 2 Cubic Feet
  • Dimensions (L x W x H): 27" x 13.5" x 18" (filter), 20" x 12.25" x 18" (sump)
  • Inlet / Outlet (Bulkhead): Two 1" / 3/4"

Manufacturer Info

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.

Comments: Good product maintenance is easy and convenient, only real issue I had was a slight leak in between sumps but it just required a little more tightening of bulkheads and problem solved!

Comments: I am very happy with this product.The wet/dry is well crafted with a large sump to hold other filtration devices.The unit has lots of water flow and performs water and air mix perfectly.The only thing i would like to see changed is the outlet hole from the sump.It is too small and restricts water flow to larger, high output pumps.

Comments: I use this filter on my 240 gallon freshwater tank. It works as advetised for my African cichlids. I tried using it on a tank full of big South American cichlids but they were too messy. They required a big time cannister filter to keep up with all their waste. That's probably not the fault of the filter as much as the wrong application.
