hi all -
i'm pretty new to this website and based on help i received last year i am trying liquid chlorine for the first time.
so far its a total flop!
1) according to PoolMath one gallon of 12.5% chlorine should add 6ppm of chlorine to my 21k gallon pool. but it does not seem to. i have been adding a full gallon a day and it never goes that high. more like 3.5-4.5 ppm
2) there is talk of chlorine/plain bleach being cheaper than 3" tabs i've used in the past. i am finding that it is costing more than 3 times the price!
in past seasons i buy one 50lb bucket for about $100 and it lasts the season. so far this season i have been using 1 gallon of chlorine each day ($5.50 each plus tax). not only is the price prohibitive but i am struggling to keep the chlorine levels high enough. a full gallon is getting used up each day and i'm back to my morning levels (pre-chlorine addition) each evening. when i used tabs in past i put in 4 tabs and chlorine consistently stayed at 8ppm exactly where i need it. i saw some threads where there was discussion of very cheap liquid chlorine prices but could not find any of these prices locally (lakewood, NJ)
these are my numbers:
alkalinity 80
ph 7.4
chlorine 6
fc 6
cya 60
i have a 21,000 gallon vinly liner pool with sand filter
at a cya of 60, my chlorine should be from 7-9. so far, its never there. maybe first thing in the morning after i add chlorine. after that it drops to 6, by night its 4. i am not losing chlorine overnight, my water is gorgeous crystal clear sparkling water. with a morning FC level of 4, i should be able to add a gallon of chlorine and get 10ppm which should last for the day. but its not happening. its not going high enough and its getting used up too fast (i have read that you can expect 2-4ppm to be used up during the day but i seem to be using more...
what am i doing wrong?
