osmolator with two pumps?

I have been using the osmolator for a couple of weeks and am very happy with it, great piece of mind. I have been having problems with low ph at night so I want to use kalk, maybe in a nielsen reactor but only at night. Is there a way of using the osmolator to control two pumps. One to use with normal top-off during the day and with a aquacontroller to switch to a second pump feeding into a nielsen reactor at night? Any ideas would be greatly appreciated. Thanks
 
Yes you can wire the pumps into a relay and then use a timer to supply the 12 volt feed from the osmo unit to what ever pump you want by switching the relay. But.

The unit has a 10 minute timer that shuts the pump down as such dosing kalk may be an issue as you need a slow drip and in this case you may need to have a second timer rest the tunze osmo unit now and again.

Now as to if this is a good idea i will let Roger come back on that one
 
It is possible to do this with a relay. I would vote against trying to defeat the 10 minute countdown though. This could be a big problem.

Was searching back through some of these threads and came upon this thread. I use an osmolator inline with a nielson reactor. What kind of problems do you run into? Will turning off the controller cause damage to the unit? The only reason I ask is because I have had some problems with kalk entering my system in high concentrations(snow storm effect). This happens when the reactor was stirring so to prevent this I turn of the osmolator while the reactor stirs. Once the reactor stir is completed I then power the Osmolator back on. I do this 3 times day via AQII. If this will cause physical damage to the controller I would like to know. I'm not worried about the 10minute countdown because I use my AQ to turn of the unit if the PH goesd above 8.5 so if the only problem is that the unit will never utilize the 10min countdown I can live with that.
 
The only thing you risk is disrupting the countdown, otherwise I see no other problem.
