My Intex SWG bit the bullet today less than one month pass the end of the 2-yr warranty. To be honest I hadn't been very satisfied with how it performed but in reality it was likely more me not completely understanding pool chemistry. So seeing how the summer weather has turned cooler here in northern VT and likely not more than a month left for the pool season I decided to take the path of least resistance and try out Pristine Blue for the remainder of the summer. Well after reading some of the threads here about PB not being a sanitizer and the likeliness of green hair, I have decided to utilize the BBB method instead. I have an Intex 15' x 42" metal frame pool with the 1000gph filter pump. The test results from today are 7.9ph, 200ppm hardness, 100ppm alkalinity, 1500 ppm total dissolved solids. Since this test was run for PB use FC, TC and CYA was not run. My last test from 7/12/13 showed CYA to be 15. I will get these values tomorrow and update. I will also order a test kit tonight if someone will please decide for me which one is best based on the above info. The big concern right now is what to do until I get a TFP test kit. The pool has been cloudy for some time and has recently improved (I can see bottom standing from the opposite side) but I'm really concerned letting the pool sit too long without chlorine. The only PB product I have added is the Pristine Check which apparently removes excess calcium.
