Alright, I installed my new (to me) 24'x42" above ground pool last summer. Had no idea what we were doing so we pushed the 'easy' button and went to Leslie's. Spent several hundred bucks on chemicals last summer and thought there had to be a better way. Talking to a co-worker, I became convinced that TFP & Pool Math would be revolutionary, so we ordered our K-2006 test kit at the end of last summer. We got busy and the weather cooled off early, so I never broke out the kit. Fast forward to this spring.
Opened the pool, hauled in 1400 gallons to get it above the skimmer, let the filter do it's job for a couple of days and then broke out the kit. Seemed straight forward enough. The test was pretty straightforward, slow the first time through, but seemingly simple. Got to the CYA test and was surprised to see that my level tested at 90-100. Typed it into PoolMath and I was shocked to see that it told me to drain half my water to get it in range!!!! I thought surely that can't be right, but after reading on here, we used tablets last season (a 3 gallon size pail total over 4 months) so I started believing it.
So here comes the confusion. I thought, before I drain half my pool and haul 12 loads of city water in, I would run by Leslie's for a quick test, what could be the harm. They tested it and there numbers were close to mine on everything EXCEPT for CYA! They said I had Zero (compared to my 90-100). I tested again and got 90-100.
So what gives? Is my 8 month old test kit suspect/expired? Is Leslie's that far off? How do I break the tie? Any help for this rookie would be appreciated. Thanks!
