I have a pool with a built in hot tub that waterfalls into the pool. Right now, I am having a hard time keeping the spa clean as I have to manually switch the two input and output valves on the pump system every day. I would like to separate the hot tub from the pool's cleaning system by adding a new pump/filter/SWG (maybe with something like this http://www.vminnovations.com/Product...er-System.html. There are hose to pvc diy adapters online).
My question is, with my main pool being salt water, will the second SWG cause any electrical issues if they are both ran at the same time? I don't want to harm any of the bathers.
I don't like to have the spa flow into the pool as I loose my heat and it causes scaling on the wall.
