Summary: I added cal-hypo and it turned cloudy immediately. And the pool is still cloudy 2 days later after the cal-hypo cloudiness dispersed throughout the pool.
CL: 3.5 ppm 1 day after adding 48 oz cal-hypo which PoolMath says will raise my FC 7 ppm
We've had heavy bather load (dogs
CYA 28.
Ph 8.1.
- 1 drop of acid demand test lowers to 7.8. Chart says I need 26 oz muriatic acid / 20deg baume to lower to 7.8.
TA 110.
Ca / CH 130.
Plaster surface.
BACKGROUND:
I live in the north so I close my pool over the winter, which means I lower the water level > 1 foot.
31.5k gallon pool, and I drain maybe 6k gal which is 20%. That is replaced by rain and snow over the winter.
It was a warm winter, hardly ever frozen, and spring came early, and it was a little green come late March so I started a SLAM. Pool is clear and walls are clean now. The SLAM was all liquid bleach. Maybe 25 gallons it took. CYA was only 25 during this SLAM.
Near the end of the SLAM I used tri-chlor to get my CYA back up to 40.
And it WAS at 40. Now it's at 28. Dont know how that happened. A lot of rain?
After the tri-cholor I switched back to using liquid bleach in 5 gallon containers.
But Ca (CH) was low, so I switched to 65% cal-hypo from in the swim. It's about the same cost for effective CL as liquid.
But it made my pool cloudy.
I also don't know how the Ph got to be 8.1. Once I learned here about tri-cholor and high CYA levels and it's negative effective on the sanitizing power of CL--and started using liquid bleach--I stopped testing Ph cuz the pool is always clear and clean. Bet we have acid rain where I am and the Ph has ALWAYS been low. Never high. I was always adding Ph+ never Ph-.
So what do you think is going on?
