On opening the pool this year, I quickly got the water clear and with very little CYA, was comfortable using trichloro tabs for a while. The TC was staying around 3.5, but with six of those tabs in the skimmer, I figured they were maintaining the chlorine levels and it would quickly flatline once I had to pull them out and just use bleach. I lost count but had put in about 14-15 bottles of 12.5% chlorine and couldn't get chlorine up to SLAM shock level. Not even close.
I added a jug of stabilizer to get my CYA up, waited 24 hours and here's where my levels were a week ago:
FC 3.5
CC 0
TC 3.5
TA 70
CH 600
pH 6.8
CYA 35
I pulled out the tabs and got very busy for a few days. Also turned on the pool heater and brought the water from 50 degrees to 85... local pool store was out of chlorine. I checked yesterday and the water was VERY cloudy. In an attempt to quickly get the levels up, I put in about 14 pounds of cal hypo. A few hours later, still almost no chlorine! Added 4 jugs of 12.5% chlorine and went to bed. Woke up this morning, still cloudy, almost no chlorine and the following levels:
FC .5
CC .5
TC 1
CYA - near zero! What happened to my CYA?
CH 500
TA 70
I realize it looks like I should add CYA, but I want to be VERY VERY cautious after the pool company screwed up the pool a few years ago with tabs and required me to truck in a very expensive 20k gallons of water.
Should I just keep adding bleach? Kind of at a loss here and definitely don't understand how my CYA disappeared... I use a good test kit ordered from this site. I scrubbed the liner really well on opening and there is no debris. Also, have brand new cartridge filters and extremely good flow on the pump.
Thanks!
