I recently purchased a 2006 Sundance Optima, 480 gallons. I am using the Nature2 cartridge in the skimmer. I am using the Spaguard chemicals. When I first filled the tub, I put in an entire bottle of Spa Sentry and then shocked the spa with Enhanced Shock, the next day. I was told to shock the spa approx. 1 /week. These were the only chemicals I was told I needed.
9 days after using the spa nightly, the water was cloudy and green with a musty odor. The dealer told me it was metals in the water and had me add in an entire bottle of SpaGuard stain and Scale and then shock the spa with approx. 2/3 of a cap.??? He is never good at giving me an accurate amount to use.
Anyway, I ended up having to drain and refill the spa because the Stain and Scale and the shock did not work.
After I drained it, the dealer recommended another entire bottle of Stain and Scale. And then the entire bottle of Spa Sentry. I decided to go out on my own and I just followed the directions on the back of the Stain and Scale bottle. I only added 2 ozs. I did add the entire bottle of Spa Sentry. The next day, I shocked it with 3 ozs of the enhanced shock. So far, the water is clear but it has only been 3 days.
My question is, do I need another chemical to go along with the Spa sentry and the Enhanced Shock? Do I
need to be using some sort of dichlor or chlorine? My dealer says no, but I think that I do.
Any advice would be great.
Thanks.
