Great idea. I was thinking of how to design something like this, but
then quickly came to the conclusion that it would need to be a controller
of some sort.

Thanks for the recommendation on reefkeepers. That looks like a
reasonable solution for less money then I'd expect.

With even less money you could go with old trusty solution
to use two smaller heaters instead of one big one.
There is very little chance that both heaters fail at the same time.
So one failed heater will not create a disaster in the tank
and with your current termometer you will detect the temperatrue off
the limit and replace the failed heater - no expensive controller
necessary..

Agreed there also but look at all the other things a controller can help
with. It cost more but the Reefkeeper 2 will shut the lights off if over
tank if temp gets too high also. It will then kick them back on after
episode is over. You can control lights, heaters, chillers, fans, power( has
wavemaker control), PH control function, feed mode and gets rid of all those
pesky power strips..
To me it was worth the cost for all the safety features like heater control
and all the other controls. I have a calcium reactor that uses the PH
function on it also on one tank. If PH gets out of wack the controller shuts
off the regulator and stops it. On other smaller tank if PH gets high it
shuts down my Kalk Reactor.

If you go this route you can put the money from the cost of a smaller
secondary heater to the cost of the controller....LOL

Been using them for 2 yrs on my tanks and have never had a malfunction on
either due to heat or PH swings/malfunctions.
