Good thing it was in the off position! 20 gallons can get hot fast. So far Ive been lucky that all my heater failures have been off rather than stuck on.Discovered that the heater in one of my 20L grow-out tanks had failed; Marineland, of course, the worst heaters on the market. Fortunately it failed in the 'off' position, so the fishes were cold, but otherwise OK. I thought that I had discarded all of these heaters years ago, and replaced them with Eheim's, but apparently this one slipped under the radar.

Thanks, so happy to have all these tanks by a utility sink now.Looking good
Water change day for me. Started with the 300 and then did the garage tanks. Having the tanks in one spot made for a nice quick change
Im just using a 300 watt Fluval e series and a 250 watt SERA heater in the 300. Originally had 2 of the Fluval but they couldn’t hack it so I replaced with the SERA’s. After about 3 1/2 years one of the SERA started to act up so I popped in the Fluval and its been working okay. So Im running 550 watts and it keeps temp fine but if I had to actually heat water the fluvals dont do that great.What size heater do you have in the 300. I have 2 300w heaters and they are not quite enough it would appear. Took 18hrs to raise temp 10 degrees and I don’t think I have seen them off at all.
