Hope I'm in the right place for this question.
In case my profile doesn't appear, I have a 20,000 gal. vinyl lined in ground pool using a sand filter. Attached fiberglass spa. Sani-King chlorinator using 3" tri-chlor tabs.
Opened the pool this last Saturday using a Leslies opening kit. Water looked OK and everything mechanical running great. Added the following according to kit directions:
Removed worms at the deep end using a hose fed leaf bag
added 1 liter Leslies Metal Free
tested ph at 7.5 and alkalinity at 140 ppm
Brushed and vacuumed, then backwashed
shock oxidized with 4 lbs Leslies Fresh & Clear - did not simply broadcast per their instructions. Dissolved in b5 gallon bucket and poured around perimeter.
added 3 lbs Leslie's Chlor-Brite (di-chlor sanitizer) and ran pool overnight.
Next morning, pool was green, so I added 1 quart Leslies Algae Control (which is their step). Let water circulate 4 hours with no change.
Hit it again that night with 4 more lbs of Chlor-Brite, which improved things, but still green.
Brushed, vacuumed and backwashed again the next day and shocked with 3 lbs di-chlor. Cloudy but not green, tested.
tested with strip, getting the following:
Cyanuric acid: 40
I'm afraid I haven't killed everything, and have always been confused about breakthrough chlorination, and would like to try bleach rather than adding more di-chlor shock. So basically, my question is how much bleach should I add, and after brushing and vacuuming once more after that, can I rely on the chlorinator to take over?
