First off, Great Forum/ Website... I have learned more about pools in one week lurking than I could ever imagine.
My father in law just cant handle the pool work anymore so I have told him I will take over. His pool has alway been cloudy, and murky. I will do my best to make this sparkle.
I am somewhat lucky in my line of work I have access to a water laboratory, so I am used to all of these tests, and do a lot of these tests daily. I have decided to go with 12.5% Sodium Hypoochlorite liquid as my choice. I am also lucky in that I can get it by the 30 gallon " drum" for about $1.56 a gallon.
He has been using Sustain products. Both the 3 inch pucks, and also the "shield energizer" fast dissolving tablets. On both containers is says 68% Calcium Hypo. It also states that it contains NO stabilizers.
He never tests or has tested his water, and just relies on the pool store to do it...no wonder every time he leaves the store he has a new chemical under his arm, and its always murky?!
I recieved my TF-100 test kit today since it will be easier to do the tests while I am at his house than getting a sample, heading back to the lab, then heading back to his house to make the necessary adjustments.
Here are my Findings...
pH 7.3
FC .5
CC 2.0
TC 2.5
TA 90
CH 680
CYA 0
His last test from the pool store showed a CYA of zero, and my test showed the same so and addition Cyanuric acid is in order. I will do the sock method and hang it by the return jet. Should I assume it is infact zero, or should I start a dosage a little less than the full? I see not to do any backwashing if pouring directly into the sand filter. What about the sock method? Can I backwash(if needed) using the sock method?
My CH numbers look high, but I am assuming it could be because he has been using Calcium Hypo for the last 6+ years. Anything to worry about with readings that high? It is a vinyl liner, no plaster involved.
I was gonna do the SLAM method this weekend, as I am off and have extra time to stay and watch the readings. I was planning on hanging the sock Friday, but was wondering if the CYA will be avaliable to help the Chlorine out by Saturday.
One last question. If it is OK to backwash while doing the "sock CYA" thing, should I be vaccuuming and backwashing during the SLAM, or just leave it alone.
Again....great website, great lessons on here.... Thank You all in advance....
