Manufacturer Info

Cobalt Aquatics was established in April of 2011 by a leadership team with over 60 years of combined Aquatic Industry experience. The three hardcore fishgeeks; Les Wilson, a former research biologist and director of marketing for United Pet Group Aquatics, Viral Surati, a pioneering high end African cichlid importer, TFH magazine and United Pet Group key accounts manager, and Randy Parham, a founding member of the Marineland Aquarium Products sales team and national sales manager for United Pet Group Aquatics got together to form the company.

From those simple beginnings in 2011, Cobalt Aquatics now features a product mix of hundreds of items from flake food to frozen mysis shrimp, to the original MJ pumps, to award winning heaters and the innovative Egg Rockers.

With a worldwide supply chain including products and supplies from the USA, Italy, Poland, The Netherlands, South Korea and others, Cobalt has grown and now occupies a 20,000 square foot facility, and employs 10 warehouse and office staff, and 4 full time and 3 part time field and telesales sales reps and territory managers.

Q
Will this pump work as a replacement for the Bak Pak 2 skimmer?
Didn't know if it would fit in the inlet and had a hole for the airline like the one that comes standard with the Bak Pak 2

A
The Bak Pak 2 now use custom Accela pumps. A standard Replacement pumps available and the item number is CR1135. A Cobalt pump will not work without modification.

Great little pump

REVIEW
Pretty quiet pump. I used the suction cups to keep it in place. I have a couple of these and they do a great job for the amount of flow they push out and work well with valves for adjusting flow. Perfect for GFO or Carbon, but I may consider a bigger pump for biopellets.
