I think that this thread has gone far unless we get everyones opinion. That will only cause hardships and headeache's. I am so sorry Steve that your tank ended in a tragic loss. To the sponsors that gave thier opinions. Yes they gave what they knew from issues in the past. YOU can't bash a guy for giving his experience and opinions. Facts are facts. But if a sensor expires after so many years and it's electronics. Then that is a flaw wires and plastics should not have a shelf life.
But to voice a debate will just get nasty. Everyone will have a say regardless on what happens.

My thoughts Steve left for vacation and had someone check his tank.
He also had his tank monitored by a controller.
Luck have it the power went off and caused it to do what ever it did causing a catastrophic event to happen with in a day or so.

Heck I was gone over to afghanistan for 7 months and my wife watched my tank and nothing happened. I have my float switch hooked up to my top off that was in my sump. But Steve's tank did and life goes on he was just letting everyone know that what hapened. Of course the owner and mike the canadian sponssor of aqua digital wos give their explanations which was said. In my honest opinion this thread should be closed to minimize any further hard feelings.

Not to take sides, but on a conceptual level, I'm with Myka on this. A smaller reservoir is less of a potential point of failure than a large one.

Why ?

We use technology to simply the complex tasks; the simple ones can be left to the dumb humans. The instructions to the warm body checking your house daily is "Take this jug of water and use it to keep that reservoir full". If they can't handle that then perhaps they shouldn't have a key

Consider the 2 possiblities with respect to the ATO and its reservoir:

1) Small Reservoir

a) Float failure and ATO pumps entire contents into tank. If properly sized, this should not create an overflow situation and is unlikely to decrease salinity to a dangerous level. The caretaker should raise the alarm on a suddenly empty ATO reservoir after a single day.

b) Float Failure of a different nature and water is never added to the tank. Well this should show itself in diminishing sump levels and the caretaker should raise the alarm that they DIDN'T have to put any water in the reservoir.

2) Large Reservoir

a) Float failure and ATO pumps entire contents into tank. Well...big mess; major salinity drop...tank crash

b) Same as above

It's worth noting that a float switch in your sump can be used to warn of situation 'b' (for both reservoir sizes).

All that being said, if your reservoir is REALLY small and needs to be filled daily then you have to ask why you'd spend money on an ATO in the first place.

Somewhere in there is a reasonable compromise and I'm guess it's in and around the 3-4 days worth mark.
