When I started this tank, a rather intelligent person on this forum suggested I purchase a spare heater. I have a 215ltr and am running a 300.
I say rather intelligent as I would have kissed their feet tonight, as I noticed my boys weren't eating. Checked, ICE cold water. Spare heater installed, all fine in under 20 mins, boys currently chowing down. It was fine earlier when I did the tests after a water change today, and am always careful to let the heather cool and off before water change, not to knock it around, keep it away from surfaces, and have it close to the filter outlet. It hasn't kicked back in since then obviously
So, 2 questions:
1/ Is it best to run 2 heaters concurrently, thermostat knocking each other out when necessary, and avoiding tonight's mishap. Or do some of you just hold a spare?
2/ What other redundant parts do you hold that tend to fail and require urgent attention?
A tad annoyed. Was an aqua one brand (feel free to advise of better) but I didn't keep the receipt. less than 3 months old.
