Product Questions

Hello, I want to get 2 heaters, in case one of the heaters fails, the other will take over. So for a 230 gallon tank, if it recommends a 200 watt heater, do I get two 200 watt heaters? Or do I get two 100 watt heaters?

Thank you!
Question by: Jaime Lynn on Apr 2, 2022, 11:48 PM
Hey there,
Thank you for reaching out to us. You would want 2x 200w heaters. That way your take is getting the proper heating if one fails.

Please let me know if you need anything further and take care!

This sure looks like the plastic/epoxy encased Cobalt heater from several years ago that was responsible for frying or exploding in many reefers' sumps, mine included, and killing much livestock. So is it from the same manufacturer? (And please don't respond blithely that it's a completely different heater.) Thanks.
Question by: Fishtitious Person on Mar 21, 2022, 2:52 PM
Hey There, thanks for the question. Cobalt no longer exists and the rights were bought out by this company. These are brand new heaters. It is presumed, however, that the issue has been resolved and that the design has been modified.

Are these heaters fully submersible like the Cobalt Aquatics Neo Therms?
Question by: Greg Kostera on Mar 18, 2022, 6:53 PM
Hey Greg, thanks for the question! These are fully submersible!

Answer by: James Johnson (BRS Staff) on Mar 23, 2022, 2:00 PM
Is it submersible?
Question by: Les on Mar 12, 2022, 1:34 PM
Yes, that is 100% submersible.
Answer by: Matt Lucero (BRS Staff) on Mar 14, 2022, 9:52 AM
Is this the same as the Cobalt Neotherm? It looks the same, but wondering if it is a knockoff or a rebrand. Thank you.
Question by: Timothy Burchett on Feb 19, 2022, 8:00 PM
This is a similar design to the Neo-Therm but is a completely different heater.
