Ok, this is my first day here on this forum. I've been trying to get registered on pool solutions forum unsuccessfully for over a month. I'm so glad I finally found you. Ok, I've been a pool owner for just over a year and been using pool brand shock and 3" tabs for sanitizer (bought at Sams) I developed an algae bloom for the third time this spring. The first two times (last year) I cleared it up using 50% algecide, but after reading pool solutions recommendations, I've gone to the BBB system. After treating with 6 gals of 8.25% bleach , my pool water has returned to the pretty blue/clear color. I bought a Taylor 2006 test box and have been using it for about a month now. I seem to be getting accurate results for all the tests with the exception of cya. All last year and this spring, I had been using Aqua Chem 6 way treat strips or having my water tested at Bolands true value (electronic tests) or Leslies with mixed results I have more confidence in Leslies for most of the tests. My test strips have been fairly accurate in comparison, but they show a stabilizer level of 150. Recently, 3 cya tests at leslies were 100, 100, 40 (after topping off about 400 gals of fresh water) and one test at Bolands that was 80. My Cya tests have consistently not even gotten up to the scale, so I'm not sure what my Cya really is. I'm got to try the waist high thing and draining half/ filing up the test tube with plain water tonight. Well, can't do that ran out of R-0013 reagent. Tested tonight, fc=.6 (added last 2 gals of 8.25% bleach)-- will have to get some more tomorrow. Cc=0, pH 7.2- 7.6 depending on which test I believe --7.6 was using OTO? Alkalinity = 130. Don't do ch test believing pool solutions advice however pool store tests show
hardness around 100. Still reading this forum. Stopped using shock and tabs thinking it would eventually lower my Cya to reasonable levels, but if leslies last test was correct, maybe I can go back to using them again? Emptying half my pool is out of the question, but so is using 6 gals of bleach every 6 days.
