Hi all, new here and looking for help beyond what my pool company can offer.
I have a 16,500 gallon fiberglass pool with a SWG and cartridge filter. I'm fairly sure my SWG is working since when I had it closed for a week or two at BOOST levels (forgot all about it), the levels were off the chart and I had to add Chlorine reducer to get it back to acceptable levels. The SWG is mostly grey/black with a little calcium deposit at the one end where it hooks up to the electricity.
Pool has been mostly clear since.
About a week ago, we had a family gathering where we had a pretty high bather load compared to normal. We closed the auto cover and kept the SWG at 25% where it typically stays. Upon re-opening the cover, we found a greenish cloudy water (algae bloom I suspected). Chlorine level was almost 0.
Over the next few days, I dumped several gallons of 12.5% chlorine shock, tested an hour or two later and it read > 10. TA was high, but I suspected the copious amounts of shock contributed to this. I closed the cover and ran the pump on high and SWG on boost overnight. Next day, the levels were back to 1 or so (based on test strips, Taylor 2006C is on its way). More shock was added and I tried lowering TA and PH using PH down.
I added more shock last night, and today I took a sample to the pool store and here are levels:
Pool temp: 88
FCHL: 1.5
CCHL (whatever that is): 0
PH: 7.6
Alk: 170
CYA: 30:
Calcium: 200
Salt: 5200
Phos: 100
I was advised to add 2lb of CYA and 3 more gallons of 12.5% shock (tossing CYA into the pool and no vacuum for 3 days).
Using the link on appropriate CYA - FC levels, it says I should have around 70ppm CYA. I was going to do the "sock" method in the skimmer instead of just sprinkling it in, but should I start slow with 2lb and further increase or just do 3lb out of the gate?
Should I worry about TA and PH at this phase? The water is mostly clear, just a slight (I mean very slight) haze at the deep end. It feels like adding more shock will raise TA, which will make the haze worse.
Thanks in advance.
