Hi all, it has been a very warm winter here in Tennessee. I tool the cover off yesterday to a dark green swamp, first time in the five years I have had the pool, thanks to this forum! Before I started shocking yesterday my readings were:
Pool is 33,000 gal vinyl
According to pool calc I added 9 96 oz jugs 6% bleach, three hours later FC read 19, an hour after that zero. i added 8 jugs @4:00 and @8:00 still read 17 FC. This morning I read 0 FC again so added my last 6 jugs and went to get more bleach. 1.5 hours later I read FC @ 25. pool is still green(1 ft visibility) maybe a lighter shade of green. How can I be getting such high readings? My reagent is about 8 months old, and I am not currently running the chlorinator.
thanks so much.
