The only downside is the price, but for the peace of mind it was worth it.

Price isn't to bad considering you get the pump.. I'd have to buy one for the JBJ..

ditto ...

I've had an osmo for 2+ years ... very happy with it.

I love my osmolator and wouldn't trade it for anything. I like the multiple fail-safes like the electronic eye backed-up by the overflow float valve, and also the ten-minute time limit on the pump. I was lucky enough to get it used so it didn't cost me all that much.

You can prevent it from popping on frequently if the chamber it sits in has more surface area since it would take more evaporation to affect the chamber's water level. The electronic eye is very sensitive!

I like those fail safes.. Especially that 10min time limit.. That might be what sways me over to the Tunze.

I have had the tunze for 5 years and wouldn't trade it for anything. I love the optical sensor it won't foul like a float switch. The secondary float switch is a perfect for peace of mind. My pump called it quits a year or so ago but I just replaced it with a low voltage sump pump from princess auto which works perfect.

Good idea, only problem with my set up is the sump is 4 compartments that are all the same size, nice thinking though. I didnt know about the ten minute timer, that's a bonus!

I have a Tunze osmolator, I am happy with it, there are a few issues to be aware of though.

One is the electronics are a little delicate, I fried one osmolator doing something innocent a few years ago - plugged in another item into the powerbar which made a spark and blew the circuit, everything else on that circuit was fine but the osmolator was shot.

A couple of times my unit has stopped working because the optical sensor head got covered with precipitated salt/calcium buildup. You are supposed to clean the optical sensor with vinegar every few months, make sure and do this before going away on vacation.

Overall it is a good unit, keep the level very well, worked well with a kalk reactor in series when I used to use a kalk reactor.

If you can handle a little fluctuation in your water level (up to an inch) I've been using the Tsunami AT1 for 7 years never had a problem. Actually never even clean it.
The SpectraPure version says it only varies the level 1/4".
They get pretty good reviews on R/C.
Tsunami AT-1 and SpectraPure controller both use air pressure to activate and deactivate an outlet.
Just don't trust the suction cups, I made a mount from a MJ bracket.
