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.

Effective, with babying

Comments: The pre skimmer is more attractive once underwater than I thought it would be, thankfully. It is highly effective at keeping oil slick from occurring. I have a 55gallon show tank and every third day I have to either add water or adjust the skimmer intake height due to evaporation. Lastly, keep in mind you will not be able to feed with floating food anymore after you install this. Overall, I'm happy with it but I may remove it from my tank someday if I become a lazy caretaker.

Comments: Please do not run a Bak-Pak without this Pre-skimmer. It does a great job of taking the water from the surface. If you don't have an ATO, you may need to adjust the depth of the Pre-skimmer every day or two unless you stay vigilant with water levels. I would not ever use my Bak-Pak without it.

Comments: First thing, DO NOT use the foam block, it only clogs and slows down the water flow. Note: the 2 small sides are now clear plexiglass so you can see the water level inside the box. I had to drill & tap another hole b/c I wanted it to feed from left side. Works awesome when the water level is just right. I had the oil slick on my reef tank and over night it was crystal clear!

Two changes necessary

Comments: I've been using the Bak-Pak pre-skimmer for two years. It is a necessary addition to the skilter because it skims off the surface water, something the skilter will not do on it own. It works great, but needs two modifications. The first would be to remove the foam that covers the intake and replace it with a plastic slit system. The foam gets dirty quickly and plugs up. Leaving the intake open completely means fish can get sucked in to the pre-skimmer. I've had this happen. Nothing happend to the fish, but you have to get them out. Second, the threads that hold the screw, which holds the pre-skimmer in place, wore down. This happened after about two years and is the reason I had to buy another. A solution would be a plastic wedge inside the box that could press up against the pump, allowing for verticle movement of the intake. This shouldn't wear down after two years.

Comments: This does a good job, however, it is bothersome to have to adjust it with the water level. Snails, crabs, etc. will find their way in it and behind as well. It also does take up a lot of room around the pump. I got it to keep out seahorse tails and for that it does a fine job so.....
