I let my pool sit over the winter here in South Texas. It was a smelly swamp when I started to clean it last week.
Had a bearing going bad in my 2 yo 3/4hp pump, it was noisy but it ran.
I started slamming the pool and got it from a smelling green to a milky blue in a couple of days, and then noticed no more progress.
The multi-port valve on my Hayward sand filter bit the dust so I got the Intex 2800GPH 3/4hp Pump with 14" sand filter and it arrived today. Cleaned the old sand and transferred it to the new filter, hooked up and did a leak test, a 2 minute backwash and then a 30 second rise, and finally set the pump on filter. Boy was that waste water green, until the backwash finished.
So i took a reading with my T100 and the FC was 0, dumped 92oz of bleach in to get it to SLAM value of 12.
Tested 1.5hrs later and was down to 8.6 so I threw in another 32oz of bleach per the pool calc.
How often should I check the chlorine while slamming? Ever couple of hours, or maybe twice a day? And I should keep it at 12ppm until I meet all the SLAM requirements correct?
Also my CYA is at 30.
Thanks for helping.
