Sorry to hear. I hope everything will be ok. This is why i always make sure my ato water just enough to fill the sum full and not overflow the sum though i have to refil itl every 3 days. I have seen some of my friends hook up their RO/DI unit directly to the ATO and got flooded floor and dying livestock because of failing float switches.

Switches are cheap to buy but costly when they failed

My setup is similar to Coleus's, I use a reservoir that is 30 gallons with a tunze ATO and my sump has room for about 15 gallons of spare water in it. So in the event of a float failure the maximum amount of water on the floor is 15 gallons if the reservoir is full. 30 gallons in the reservoir will go about 2 weeks before it needs a refill. Long enough for a short holiday. Ideally the sump would have excess room for the total reservoir water.

Same here both tanks run on a reservoir. I just refill them when they run low.
Sorry to hear about your tank hope it all recovers.

yeah tank will turn around nothing i can do now except share my experience. If that tunze auto top off ever runs empty is there a shutoff for the pump ??

It will only run for approx. 10mins continuous then time out and shut off, it then has to be reset.

I also have the timer when the ATO pump run. This way, my pump does not run all days though the reservoir is empty

Glad I could help.
 

Might have room for one or two more corals.
