CPR has taken the proven technology behind the Bak-Pak 2 and the Bak-Pak 2R, and created the new Bak-Pak Dual Pak. The Dual Pak provides a complete hang-on filtration unit for tanks up to 100 gallons that incorporates two proven skimmers with a biological filtration chamber in the middle. Using proven Rio Rejuvenation Venturi technology, the protein skimmers are flooded with bubbles for constant removal of excess organic. The biological chamber utilizes CPR`s Bio-Bale biological filter media to provide maximum surface area for beneficial bacteria to colonize. Simply hang the Bak-Pak Dual Pak on the back of an aquarium, plug in the rejuvenation venturi powerheads, and enjoy worry-free operation.

Powerful Skimmer to consider
I've been using it for about 3 months, and I first experienced some water leaking from the unit. After a few email back and forth with their tech support team, I finally managed to stop the leaking. My tank is only 55G, I am happy with turning one head ON only, but I do have a flexibility to use both in future for my bigger tank. On the other hand, due to the weight of this unit (with water) is quite heavy, I have to use a piece of wooden stick to support it so that the skimmer will not tear my tank apart. On the other hand, it's indeed very noisy from the little air intake value, but it's inevitable though. After all, it's serving a good purpose, and I am collecting all dirt constantly from my tank.

It is too large to fit my 55 gallon aquarium.

CPR AQUATICS HAS GREAT CUSTOMER SEEVICE
Very easy set up. CPR aquatics has great customer service if you have any questions or you lose one of the pieces like I did. They were very helpful. If the directions are followed in the troubleshooting section the micro bubbles disappear after 24-48 hrs.

garbage-couldn't tighten enough to stop leaks
Total garbage. Bought it two years ago but didn't set up my 135 saltwater til today. Could not get the seals to stop leaking no matter how much I tightened them. If I tightened any more I'm sure the plastic would have cracked. Finally threw it outside cause it's obviously way past any warranty.

So far very good. I am wait to see if I can get the micro bubbles under control after the tank finishes cycling.4/21/15 The filter/skimmer works great, it has been about 3 months now. My water is clear and my parameters are inline. I had to make a couple of tweets to get rid of the micro bubbles so I made new outlet into the tank with using a defuser method with 1.5 od clear acrylic tubing. I had an issue with one to the power-heads and customer service took care of the issue very quickly.

Great after modification
I bought one of these for an Oceanic BioCube 29. I was going to buy the single CPR Bak Pak, but for the price the dual is better. The Accela pumps are loud. My tank is 30 feet from my bedroom and even with the bedroom door closed it was loud. I had to turn it off at night and hated it the first night. The micro bubbles were everywhere.This 4 stars is a stock rating and I was being generous.PROS- Well built. Fits for just about all tanks.CONS- LOUD. Louder than I would have believed if I read it in a review. Micro bubbles like crazy and they wouldn't stop.I ended up modifying it on Day number 2 of owning it. I swapped out the Acella pump for a Red Devil SP3 with a homemade 3/4 inch manifold. After the modification it is easily a 5 star skimmer. The mod also ended the micro bubble problem immediately. The SP3 pump made mediocre skimmer performance into an excellent skimmer.Would I buy again, Yes. But I would have hated it without the different pump.
