I just recently changed the sand in my filter after 5 years using the same sand(New pool) because I was having problems clearing up the green water upon opening.
So..... I have noticed a trikle of water on occasion coming from the top of the filter....beneath the band clamp.
The reason I am writing.....since changing the sand I have noticed a drop in the flow coming into the pool via the jets,should I be concerned ??
My new pressure gauge runs between 8-12
Thanks for all your help
