OK...just bought a house in July and it came with an in-ground, 22,000 gallon salt water pool with an Intellichlor SWG. The pool was basically trouble-free all summer. Had to add Muriatic acid a couple of times to lower the pH...but other than that it's been pretty easy.
Last night the red LED came on on my Intellichlor...which means the salt levels are reading low. I don't think there is a way for the Intellichlor to tell me exactly HOW low they are...just that they're low.
My question is how do I go about bringing up the salt level? Do I need to buy a salt tester? I don't think the test strips I'm using measure salt...so I assume that's a separate tester to buy...more money spent.
