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 the 150watt work on a 46 gallon bowfront or do I need to buy the 200watt? I'm nervous about getting the higher watts with all the issues they have had. Thanks for the help!!

Q
how many units will I need for a 225 gallon tank with a 50 gallon sump?
Also should u get multiple smaller units or less with higher watts?

You would need 3 x 300watt heaters and 1 x 150watt heater. A lot of people use 2 (or more) heaters in their tanks just in case one should fail, then they have a backup. If you want just one heater, the JBJ True Temp Digital Controller w/ Heater - 1000 Watt would work well for you.

REVIEW
I had a cheaper glass 300w heater on my 55g that would fluctuate by 2-4 degrees. This heater only drops around 0.7 degrees when ambient temps are 17 degrees colder than my target temp. It's expensive but if you're looking for extreme accuracy and less fluctuations in temperature this is the best o...Read More

I finally totally imm...Read More

Easy to read, durable, accurate.
REVIEW
I have two sets of the 300W in my big tanks and a 100W and 50W. All of these heats preform very well and are worth the money. You can set them and forget them. Plus you don’t have to worry if they get totally wet. Great durability as well!
