Manufacturer information

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.

Yes, I would recommend this.


Pros: Bright color easy to see, Very flexible and strong

Cons: Sometimes comes crimped In package

Flexible and stays on hose barbs. Strong too. I’ve had different colors and treat them the same but for some reason this color seemed to change to brown and get dry quickly when only used occasionally. Comes in handy if you like drip acclimating your animals and keeping track of hoses more easily. I may try using this for dosing too
