Aquael vs Cobalt neotherm

[Mikeb86]

I am trying to decide between the aquael ultra heater 150 or the cobalt neotherm 150 for my biocube 32. I really love the form factor of these 2 heaters as they fit nicely in my rear sump. I have seen a lot of comments on YouTube about the cobalts blowing up but I think those were the 200 watt plus models. Anybody have experience with these type heaters? Which one is safer?

I've owned several of the smaller Cobalt neo-Therms and they are my favorite heaters. They kept my nanos at rock solid temperatures.

The only downsides are they are pricey and run longer than some glass heaters

Pretty much any heater has the potential to blow up if you run them dry, especially the higher wattage ones.

Ok thanks, I was originally going to get the 150 watt one , after some research I may get 2 75's and attach to a controller.
