Hi Guys, ti has been a while. Ever since taking over my own pool a year ago, things have been great, since starting over, doing two SLAMs etc.
Anyway, even though it is winter, here is FL, the kids still use pool when temp over 72/73 degrees, so I have been testing CL, PH , adding acid to keep at 7.5 ph and scrubbing , every week.
Anyway, I noticed yesterday that PH was at 7.0 - when all winter it has been rising to 8.0 and I have been ADDING acid.
So, I decided to do more testing and got:
CL - 3.5 (SWG set to 60% for 6 hours) which is high - I have been steadily increasing over last couple of months to maintain CL
TA - 20
Salt - 2600
So, I added a bag of salt, 9lb of baking soda , and SALt now at 3100 and TA at 80. PH was up at 8.0 , so I just added some acid.
I figured I might as well test the rest, as I was concerned on CL level , turns out , my CYA is at zero (well at least nothing shows on full test tube )
So, mu question is, is it possible to drop CYA from 80 in August to zero now? Would this be due to rain?
Can it actually be zero, or is there something wrong with the test chemicals?
Pool Math table says I now need to add 192oz of liquid stabilizer - this seems a lot , right?
I think this explains why my CL level has steadily dropped over winter from 8 to 3.
On the up side, my high CH level of 460 is now down to 300 .
Any thoughts on how to go about this CYA issue? OR should I just stick to the pool math table as always?
