The situation is this: I have "shocked" my pool 3 times this season and will soon do the 4th shock. This is getting old and expensive.
As it progressed the opening of the pool has been tedious and frustrating. I am a novice to the BBB method. After shock failure due to bad instructions on the granular pool supply tx, then pump, then broken plumbing, twice; the pool is still dark green. The mechanical failures always happened the day after I started shocking w/ chlorine followed by days before the repair was completed. So I start from square 1 over and over. !)
I do not have my TF100 test kit yet, but it hopefully will be delivered tomorrow. But, in case the kit does not arrive I am wondering if the cya reading of the pool store H2O test from 2 weeks ago would still be valid. The only thing that has been added to the H2O is liquid chlorine bleach.
Before the reading I had increased the alkalinity w/ baking soda and all the other readings were good. My cya at the time was 46 which seems a nice place to start to see what my pool needs in the long run. According to the CH/CYA chart my shock FC needs to be maintained about 18. I understand that should be maintained and checked frequently. So will cya change in 2 weeks, with circulation about 5 days total, lots of CH in 4 days scattered through the 2 weeks in dark pea green water?
Another ? Is it necessary to test, approximately, hourly during the shock tx? I would think adding the CH in the late afternoo PM. My plan tommorrow includes a vacuum with the H2O by/passing the filter which will decrease the amount of pool H2O to be tx'd, then refilling.
I also am hoping that starting the shock in the evening will help reduce the amount of CH lost. My dinky test kit does not display CH over 3ppm. Fedex typically delivers late afternoon, and I am hoping I won't need to test FC during the middle of the night. Then I can start the "real" testing with the kit after studying the inst. the next morn.
I am looking forward to my test kit, but I also really want to open my pool ASAP, it is blazing hot and humid in mid TN right now, 90° tomorrow. I have 20 gallons of liquid CH waiting to tx my pool (I hope it is enough) I have never made it past the is day of chock before I take a giant step backward w/o circulation for days. Aaaaarg! This has got to work!
And my Dad insists I have to use the Baquacil Flocculant he purchased for me, I don't want to use it and I have to prove that I don't need it before he will stop. I told him I would take the products back and return/credit his money. I figured that would make him happy! Even credit would be OK, since I plan to only purchase a useful tool or something cool from the pool store, not chemicals.
I need this to work. Is there an "average" # of days to clear a pool filled with dark green algae? My real queation is "How quickly can I get this done?" I hope someone can make sense out of these ?'s
