Hi, I just set up an Intex 16' round Ultra frame pool. It has the Krystal Clear Salt water system. Capacity is 5,000 gallons. I put in 120 lbs. of salt and ran the pump for 24 hours as per the manual. I then got the SWG running at the 2 hour/day interval. I tested it after this for copper level and chlorine and had nothing so I ran the boost cycle which is 8 hours of the SWG and then retested. It seemed like the copper went up a little but I am still getting nothing on the chlorine test. I am using the HTH 6 way test kick which I guess is not the best but it is all I have right now.
I added 1.3 lbs of cyanuric acid. When tested I am not getting anything. The vial fills all the way past the 30ppm and the black dot does not fade at all. I have read on here that it can take a week to get an accurate reading on CYA though.
My other readings are: TA-90, Hardness-70, pH-about 7.2 and not a hint of yellow on the chlorine so I don't know where I am at there.
The water is clear but there is a slick film on the sides and bottom of the pool. My question is how should I proceed with getting the chemistry right? The Intex manual says free chlorine should be between .4 and 1.5 ppm which is quite a bit lower than the 3-5 recommended on this site. Although I guess SWG pools run a lower chlorine level. Do I need to get my pH up a bit? Do I need to add chlorine or just run the boost function again? I am unsure on how best to proceed and would greatly appreciate some direction. Thanks a lot.
