so, we can finally see the bottom of the pool except in the very deep end...there are lights in the pool that I didn't know were there haha. In any case, I don't understand why putting in the amount of chemicals that I am is not getting me the correct increase in ppm. For example...I've put in almost 4 pounds of cya...still not registering on the test -- and I am sure I am doing it right. ALSO, when I have put in a LOT and I mean a LOT of bleach (20 gallons in 2 days) the highest I have gotten on total Cl is 4-5 and FC is 3-5...it sticks around for a bit but based on calculations it should be getting 10ppm on the chlorine when I add in 182 fl oz x 2 of walmart brand unscented bleach -- instead I'm getting only about 3-4 ppm -- I've thought it was 16k gallons(pool installer said this based on freeform they use a conversion) but the pool calculator (3.5 ft deep shallow end, 5.5 ft deep end) 18x36 free form...pool calculator gives is 21000 or so gallons based on rectangle shape ... Any further advice there?
