Hey everyone,
I have a 350 marquis spa that was new 2 months ago. Started with the spa frog in line cartridges but quickly realized that was not keeping appropriate levels of chlorine in the tub. From there I started reading about the dichlor and bleach method and adopted that will little to no issues for the next month. My cya was a little high at 50 and my calcium hardness was 250ppm from following the spa frog instructions on the first fill. I decided to empty a little over half the tub to get cya levels and calcium levels down. When I refilled the volume I tested and found that I had .6ppm free chlorine, 30 CYA, 50ppm TA, 140 Calcium hardness. I added borate to bring up the level to 50ppm and then added sanitizer. I read that I'm supposed to get the original shock level to 10 on refill and let it come down. Since my CYA was in the appropriate range I did not use dichlor and went straight to bleach. To raise the FC from .6 to 10 I added 6.8 oz of bleach. I came back to test the spa later and the FC is only showing 1.6 and I decided to check combined chlorine and its showing as 12.4! I am using the Taylor 2006 test kit and I have an ozonator. Where do I go from here?
