Been using TFPC with my pool for a few months now and have great results
TC maintained between 4 and 8
Manually vacuum 2X weekly minimum and brush every other evening upon addition of that evening's bleach
Have been noticing dirty areas in a few consistent spots for the past couple of weeks.
I adjust the returns accordingly, however, still have dirty spots somewhere within about a day of vacuuming
This has concerned me, however, from what I have read on the forum, a sand filter is not the best with regards to filtration and have chalked it up to just having a sand filter
I remember a mention of adding a small bit of DE to a sand filter to increase filtration and was wondering if this, in fact, was a method that was accepted?
Is there a thread already dedicated to this practice?
Thanks in advance
