| Re: Does too much heat kill coral? As a bit or additional advice. Most aquarium heaters are junk when it comes to being reliable, and the thermostats in them fail easily, often in the on position.
I highly recommend getting a temp controller, similar to what is used for a chiller, and use that to control the heater.Yes they are somewhat expensive, about $120 - $200, but that's cheep compared to replacing corals and other livestock. |
