May I use aquarium automation for a Spa/Hottub like Milwaukee PH Controller?

Hello All

Have a look:

Is it possible to use this for a hot-tub chemical feeding?

Maybe just salt water + PH down automation ?

If I cannot do that - please tell me why!

Thank you !

 My question would be why?   Just get a aftermarket salt generator if that's what you want.   If your doing it for PH doesn't make sense.

 I don't even have one for my aquariums.  The controller just monitors PH.  You would have to get a dosing pump along with it.  i can see the use for one in a fish tank especially a breeder tank not so much a hot tub.

Thank you for your comments!
Here is an explanation :
I have a cottage too far to visit it every week, so I need some automation and monitoring.
Salt water - Agree - it is the way to go but it will raze PH.
So I need a system to lower ph if it is too high as well as to check chlorine level.
I can use Arctic Spa Boy system to monitor and control chlorine level but it does not inject Ph decreaser.
So why do not use Fully automated PH controller used for aquariums ? Simple, cheap and ready to go solution.(it has dossing pump)
Just an idea at the moment.
Thanks!
