Unless of course you run in to my previous 2 malfunctions. One exploded, and electrocuted my anemones as well as shocking me. The other developed a tiny pin head size hole; must have leaked something cause it just about wiped out my fish population. Both heaters were on Ranco controllers.A heater should ALWAYS be run off a controller so it will shut down when it breaks..no heater can ever be trusted 100%.
I personally like the Ebo Jagers - reliable to the temperature they are set for.
The BEST thing you can do when purchasing a heater is to buy 2 of them instead of 1.
For example: If you need 200Watts to keep your tank at the right temp - purchase 2 100W heaters. If one ever breaks your tank will not get overly cold and if one ever overheats your temp won't cook as quickly and you have a chance to find the issue (but then again you will have them on a controller so the controller will shut them both down if there is an issue )
I think it's a right of passage in reef keeping to roast at least one tank because of a heater malfunction.ugh of all the issues with these heaters and the technology of light skimmers and everything else y hasnt a company built a GREAT heater?
