Hi everyone. I discovered this site last year and have learned a lot about caring for our pool. Just starting BBB at the end of last season. Now opening up pool this year and tested chemical levels after bringing water level up to full and running pump for 2 days.
With TF100 test kit the levels are: pool store levels are:
chlorine: orange colored
pH: 7.2-7.5 pH: 7.9
FC: 97.5? FC: 9.6
CC: .5 CC: they don'tmeasure this specifically but am I right that it's .4
TC: 98? TC: 10
TA: 90-100 TA: 85 TA adjusted: 80
CH: 160-190 CH: they test TH: 113
CYA: 40 CYA: 17
Borates: 30-50 Borates: 38
When doing the CDT, I was putting in so many drops with no change in test color. I had read somewhere to add regular water and then multiply the drops used by how much extra water added. Therefore I used 30 ml of water (10 ml from the pool) and it took 65 drops to change color back to clear. Did the math 65 x 3 then divided by 2 to get 97.5. Did I do this right?
In March the weather was in the 80's here for several days and I was not about to open the pool then. Advice from the guy at the pool store was to put in 4 gallons of 12.5% chlorine so algae would not grow. I think that's why the chlorine levels are so high, but is 97.5 possible or did I do the math wrong? Any thoughts of what to do? The vinyl liner does not look bleached and the water is clear. Some dirt and stuff on the bottom but no algae. LOL.
Thanks for all the help you give to pool owners. BBB is the way to go. (Got the pool store levels just for kicks )
