I have been passing on my new found knowledge of TFP to a neighbor of mine with an above ground pool.
He thinks I am nuts for how much bleach he is buying.
Here are the test results.
24 foot round
100 pound sand filter
FC 16.5 (33 drops)
Passed OCLT a couple of nights ago and it has been holding Free CL
Water is cloudy.
I looked for channelling in the sand and nothing.
While I had the top open I thoroughly flushed the sand with water until clear.
I added a skimmer sock and DE to filter 2 days ago no improvement.
Could the filter be broke, I know his pressure guage is broken, but when I vacuumed there was a noticeabl reduction in return pressure. No sand in return.
I am kinda out of suggestions unless POP is the suggestion.
Thanks for any help.
