I need to first admit that I have not employed the 100 % TFP way .
We have had lot of rain in Houston since past 10 days or so.
This past saturday night ( may 16th) I shocked the pool but on sunday morning after all the rain, I found my pool to be greener than ever.
So I decided on SLAM on Monday.
My CYA from Leslie's test on sunday was 70. ( I have ran out of the CYA 013 regent test solution).
my CYA 013 regent test supply shd be coming back on friday ( may 22nd).
Here are my nos from morning-
20,000 gallons chlorine pool.
PH has been 7.4
CC < 0.5
CH - 250
As per the poolmath chart at CYA=70, my shock FC is to be at 28.
My FC last night was at 25 and so I added 1.5 bottle lbs of shock late last night. This morning was at 27.
My 1 problem has been that I have been slamming using Clorox shock. These are the 2 products that I have used
Both I know have dichlor which I understand is not the best idea.
One positive note abt this clorox spa is that they advertise that it does not increase your PH. So far I can vouch for that.
I will check tonight at Leslie's to get my water tested and find my cya number. I can't wait till friday evening to find out.
I hope I have not tripped my CYA.
My questions to the TFPexperts are -
(i) In case my CYA has exceeded, should I give up and then drain ?
(ii) In case I am still below 100 CYA, should I be checking for the FC based on the new value of CYA.
(iii) should I look for the target FC of 28 for FC of 70 or the mustard algae shock value of 39 ?
(iv) what should I really use for raising the FC level now?
I will be working from home on thursday , so hoping that I reach the level and then maintain it.
My pump has been running 24x7 & I had put new set of filters on May 2nd.
Thanks in Advance.
