ATO

[Wayne]

What kind of failures might occur with the contollers? Do they have backup safetys?

[Reefer Rob]

You can set the maximum time the pump will run to prevent an overflow in the case of a stuck switch. If you can set up a gravity feed it is the simplest system. I ran that for 4 years without any problems even though I had a controller. I've only just started using the ATO with the Profilux on my new cube because it is sump-less.

I have a profilux and the amount of safety you can add is endless. Max on time for one which is fairly full proof but you can also add additional float(s) for back up as well. Plus it was alarms which can be silent or audio and you can even add a module that will text your cell if a problem occurs.

Wayne,

If you're not looking to spend a lot, check out Autotopoff.com. I've heard good things about their products but no personal experience to attest to.

This is something that I am considering, but at this time I don't think its going to be possible. On my next tank I will invest in a system just so its less maintenance

Unfortunatly I have no room in my stand for a bottle. Especially if I every put a reactor in there . I do like the idea because even if it "fails" its only going to dump a certain amount of water in and no more.

I like the simplicity of the system... But on the other hand I do like dry floors, is one float switch enough of a safety?

I would still use 2 for redundancy.
I have DIY'ed a similar one but bought the float switches off ebay and the rest were stuff I had lying around. It has been a little over a year and so far so good no failures yet nor has it ever tripped the second float switch.

"Redundany" in this case that means dry floors! I like that word

Do you have 2 "max water" switches? Or is it like the BWI/Autotopoff one with 1 fail safe float?

[intarsiabox]

The Double Switch Controller at autotopoff.com has a main float switch and then an emergency float switch set a little higher in the event that the first one fails. Not a bad set up for $50.

Wayne, I use this one. It has never failed me yet.

Along with a Aqua lifter Pump, and a water container of some type, and some hose.

Just another option. Doug
