I have a new Arctic spa with the onzen swg. Dealer did not give me much help withe the start up. After chasing the FC/PH/TA levels around for a week or two I thought that I should read up on what I am doing. Thankfully I found this site.
So where am I today. Went out and bought a Taylor K-2005 test kit and got the following results:
FC - 2.5
PH - 8.0 (acid demand of 4 drops)
TA - 120
CH - 50
CYA - didn't read at all (water never turned cloudy and the black dot never went away)
According to the little wheel that comes with the test kit, my water is close to balacned (+1) but at the wrong point.
My questions are:
1) Looks like I need to add calcium to get the CH up. Will the water rebalance around this new CH level, or should I adjust TA and then PH afterwords?
2) Any ideas why my CYA is zero (or really high)? As this is an outdoor above ground spa with a cover on 90% of the time, do I need to worry about CYA as UV should not be much of a factor?
3) The Onzen system should generate FC, but does it generate CYA as well or do I need to add this. I have used a little spa oxidizing shock chemical that came with the spa. It is chlorine free potassium monopersulfate.
Sorry for the long message. Any help would be greatly appreciated.
