If they can only find you a 'tee', a short piece of hose on it with something jammed in the end and tie strapped will get you by

I use a golf tee to plug unused lines!! Lol

Classic. LOL

9 yr old just everted a flood. Left house to pick up fish order and forgot to turn ATO off after last experiment. Called to say alarm was going off (disturbing his xbox gaming) pulled pump and turned it off. Way to go Dawson. :smile:

Is the tube going from the ato into tthe sump submerged?

If the ATO, reservoir is above the sump you don't need a fancy controller just get a float valve similar to what's in a toilet. Make sure it is all plastic as brass contains copper and will quickly dissolve in rodi water and nuke your tank. Use syphon to top up and then the valve shuts down flow when desired level is reached and should resume syphon once the level drops and opens the valve.

The OP is running a Tunze Osmolator system

I get that, what I'm getting at is why spend the money on something that is having issues. ATO systems are great but once you get syphon involved they can be a headache and messy. Sell it and buy a mechanical float valve. I believe ufa sells them for about 50 bucks which is peanuts compared to a tunze.

No, it definitely isn't submerged. Sits a couple inches above high water level.

Only problem is that I Still need a pump to start the flow. The tank is sitting at the same level as the sump, it just sits 5 inches higher than the sump and probably 8 or more inches over water level in sump.


I'm thinking of adding a float shutoff to the current setup. Could work >>>>:wink: will have to experiment some more.

IMO ...
You either run a true ato, or you don't ...
You can run the system suggested above, which involves a float valve installed through the side of your sump ( or some other rig ), or you run a true ato, which you already have .......

I don't see any problems with the setup you have
You only need to adjust the hose

To suggest you turn away from what you have and use floats and such instead is going backwards ......

Bothers me when people don't read the whole thread .... :rolleyes:
