In my 240g I had a 300watt heater in each overflow box. I they keep burning out though. Any advice? I usually get eheim jager heaters. Any suggestions on a better heater set up?
I have 2 theories here.
1. They aren't receiving enough water coverage to properly keep them from burning up. They need to be submerged 24/7 if on.
2. the enclosed overflow box isn't allowing for enough heat dissipation and is causing them to overheat and pop.
I would try moving them into the sump or the tank.
Or they are never reaching temp, on all the time and overheating. Just throwing out what I think is going on with them, could be anything really though.I have pondered with these ideas as well my thoughts though would be that the heaters are suppose to shut down when the water reaches the appropriate temps. If the water in the overflows got to hot would think the heaters would just shut off.
Sadly I do not have a sump on this tank. I am running 2 FX6's with the inlet connected to the stand pipe thats cut at 12" to make sure there is always water going to the filter.
this. If you are burning out more than 1 that fast I'd bet this fixes the issue.Why not try submerging them in the tank instead of the overflow boxes, as an experiment.
If they don't burn out in the tank, then placement in the boxes is the problem.
