I have a 75 gal
community tank. The present heater in the tank is the third heater to go bad in the last year and a half. One heater just quit, the last two would not hold a temp. The present one worked very well for 8 months or so, but a week ago lost it's control, running up the temp 5 degrees over the original set point.
I have a large pleco in the tank that "rearranges" things, and I'm wondering if its thrashing around and banging the heater might be the cause.
The present heater is a Rena, and until this week kept the temp within about .2 degrees. Are there anu "bullit" proof, or in this case Pleco-proof heaters on the market?
