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.

REVIEW
When I ordered this I happened to see it on a search for replacement parts for my CPR Bak-Pak. My unit did not have one, figured I should be using one. I installed it. Not sure that it added any efficiencies to my Bak-Pak collection cup. Fits nicely on the outside but does not slide into the unit. W...Read More

REVIEW
I bought the O-ring for an older backpack that I had bought used without the o-ring. For such a cheap simple piece it has helped a lot with skimate collection.
