I am making some headway.
I have been adding bleach daily to get to 5ppm. On Thursday, I added 32oz (weight) of granular stabilizer to the pool in a white tube sock hung under the pump return. My skimmer basket was too small to put it there. As of last night, it was all dissipated. I would put my pre-stabilizer CYA reading at 0-10
This morning, FC is less than 1, probably 0.5ppm. CYA is 25. The tube only fills halfway, so I assume I am just mixing another batch and keep filling the tube up?
Once stabilized at my goal of 40, how often will I have to add stabilizer? Should I be getting larger containers?
Does bleach lose effectiveness? When I added yesterday, I used a container of liquid Pool Shock containing 12.5% vs the 10% household I have been using.
Anything more I should be doing at this point?
Thanks
Hello,
CYA or stabilizer does not dissipate or evaporate. Its purpose is to slow down the chlorine or bleach evaporation from pool water.
I would make sure that when chemicals are added, that the amount added is proportional to the pool volume to ensure the correct concentration (ppm) is reached.
Once you reach your CYA target level (say 40 to 50 ppm), you should not need to keep adding unless you lose water like when it rains and the water overflows your pool.
Unfortunately Bleach or chlorine will evaporate daily due to many factors including ambient temperatures, wind and pool usage.
In my pool, for example, during summer time, I lose between 2 and 3 ppm of chlorine per day so I have to compensate by adding chlorine daily to my pool.
The pool has a chlorine addiction !
Based on Poolmath here, and the pool volume, you determine how much chlorine you have to add to compensate for what you lose daily.
Sooooo.... Say you add chlorine and get to 5 ppm today. Tomorrow at the same time take a sample and see by how much it went down.
If you lost 1 ppm then add the chlorine prescribed by Poolmath to increase the concentration by 1 ppm.
BTW, I only use liquid chlorine.
I hope this helps...
