I have an osmolator on a 120 Gallon tank with about 30 Gallons in the sump. Granted system size does not absolutely determine evaporation rate but mine isn't running that often that it is limited to the rate of the pump and I would love to have a system that had this problem

Continuing with this derail ... FWIW, I am running an Osmolator on my 280g, and with 3x400w halides, 4x54w t5's and 2x24 t5's, there is a fair bit of evaporation happening.

But the Osmolator is defective, it doesn't shut off (it gets stuck on). In the meantime while I am dealing with Tunze service about this, I just plug it in for a few minutes twice a day and unplug it when the water level gets to the level it should be.

Point is, the supplied pump is not slower than the rate of evaporation.

One thing you can do however, is get a 12V relay from an electronics supply store, splice that into an extension cord, run it off the top up and then you can run a Maxijet (or a solenoid valve or whatever you want) instead of the suppliied DC pump. You can also buy such a relay from Tunze although I don't see it listed anywhere, but the DIY project would be pretty simple (and probably around $10-20 in cost).

You say that now, just wait until you are trying to figure out how to hook up the ATO on your new controller.

Ok, I'll shut up

Please done give Brad and ideas that involve him doing anything electrical over pushing a button or plugging it in.. I have seen what happens when he does wiring..

Shut up!! It was a small fire!! Although I did zap myself last week, but that wasn't my fault!

No. I put an old hagen powerhead in the tank, and then my arms. Then I touched the reflector and slam, got jolted out of the tank. It's the powerhead's fault. And quit derailing my thread.

I was going to suggest this after Greg posted about the unit not being sufficient for his setup. I've seen that pump flow tho...I have a super tough time believing it pumps slower than the evap. Or maybe I'm not fully understanding. Maybe the reservoir the sensor is in is very large so when the 'eye' detects a need for water it can't make it up in 10 min. I think if you make the return pump area small enough so evaporation makes the level there change very quickly...the unit will be doing far more frequent topoffs and none even close to 10 min in length.

But umm...on topic...I like my standalone doser. If the main unit is as easy to use at it is I wouldn't have any issues. I'm a computer nerd to a small degree so maybe it helps I'm not sure.
