I am not having any success in seeing any measurable (Talyor test chems) pH or CYA increases on a newly-filled pool
Being a cautious sort, I want to see a testable change in the correct direction, rather than blindly toss in what might be "too much" of any chemical
So, starting with a fill of 4545 gallons of city water into a small vinyl above-ground pool, I have reading as follows:
Added 120 lbs of salt for the SWG to reach the ~ 3K ppm required.
Had a FCL of "0", so added 3oz of trichlor granules ("Shock"), as PoolMath said that would bring me up to 4.5 FC, and the SWG was running to add at least enough to overcome sunlight consumption.
Next morning, FC 3, CC 0.5, TA 40, pH 7.2, CYA <30
Added 9.3 oz 20 mule borax with PoolMath says should give me 7.6 pH
Added 8 oz of 100% CYA stabilizer to get a claimed +15ppm CYA
Next morning, FC 2, CC 0, TA 40, pH 7.2, CYA <30
Added 4 oz more 100% CYA stabilizer
Added 3.6 oz more trichlor shock
Next morning, FC 5, CC 0 TA 40 pH 7.2, CYA < 30
I am not moving my pH or my CYA at all here - the test tube has a minimum reading of 30, and the black dot is clearly visible at 30.
pH is also just not moving, and we've had no rain, nor has water been added. There has been sufficient time (several days) for things to mix and reach a consistent level.
The SWG is clearly "working" as the little bubbles can be seen coming off the electrode plate assembly.
I had this all manageable last year, don't know what stupid rookie error I am making here.
Can I buy a vowel?
