4 days into BBB, a few questions please
Friday I drained and replaced 12,000 of my 15,000 gallons in order to get a fresh start and get rid of a very high cya.
I've been using pool math and feel I have a pretty good handle on the system and really appreciate this site and the great help.
Here are my latest numbers from yesterday afternoon.
FC 3.0
CC 0
PH 7.6 it has been rising each day on its own
TA 130
CH 150
cya 50
my question is related to the cya relationship to the chlorine.
I've been using 4-6 for my FC min/target
it seems I've been losing 3-4 ppm each day which concerns me since the water is cold and nobody is swimming.
Pool math suggested about 96 oz of 8.25% bleach so I just put the whole 121oz jug in. I did an overnight test and saw no loss so I don't think I have anything using it up and the CC level of 0 would confirm that?
i bought the bleach at Target. Store brand. Maybe it's weak?
I think I need a little clarification about the cya relationship. I understand the higher my cya is the more bleach I need. But should the higher cya level help preserve the chlorine? In other words should the level hold better with higher cya? If I up the target FC to 10 should a loss of 3 ppm per day, does it make sense I would be at 3 in two days? That's just an example to try and understand what's going on.
thank you all very much!
