Thanks for the replies. You both make it sound so easy!
I have had a Marquis Vegas for about 2.5 weeks now. It is my first spa, and I'm feeling very confused. I set it up with an @ease cartridge kit/start up packet. I tested the water and added some alkalinity increaser as advised by my dealer; this brought the Ph into range too (he was right). All that I was told was that I needed to add chlorine granules after bathing to keep the water clear and to test and adjust the water on a monthly basis. I love that the dealer wants to make things easy for me, but does this sound right?
Also, I'm not sure how much chlorine granules to add or where to set our @ease cartridge. Our tub gets daily usage by 2 - 6 people, and the dealer said we would probably want to set it at 2. He's probably right, but I'm more of a follow a recipe kind of person so doing things by feel, or what looks right, feels a little weird for me. I thought this was supposed to be rocket science!
