Auto Topoff device

[Samw]

Thanks for the info Doug. I had been following the Osmolator thread on RC before I posted here so I have been able to get as much info as I possibly could. The Tunze website had not be as useful as I had hoped. I had a hard time understanding their English and I know others have as well judging from what I read. By just looking at their website, I would not have known that the Osmolator Universal model does not fit my needs and that that I need to buy the screw holder separately.

$120 seems a lot for the small Kalk dispensor. Do you think this could be a DIY for a fraction of the cost?

I think you should get the Osmomat. This way, you can use it in either the sump or in the tank and if you change your mind later, you will still be able to use your auto-topoff system (assuming the Osmomat works for both).

J&L carries the Osmolater Universal and not the Osmomat. But they said they will bring some in.
