I bought a house with a swimming pool a couple of years ago. The pool was put in 2007. I decided to change the sand in the filter. (I know there is a debate about needing to change sand..) Anyways, I opened up the pool yesterday. I live in Arkansas so I should of opened (or not close it) earlier. I have tons of algae this year. It was the yucky kind that floats and in pieces.
I was wondering about my sand filter. I noticed that when I was backwashing...the water wasn't that dirty. Today, I backwashed it a couple times, and the glass (on the filter) showed a little bit of dirty water more brown than green.
Is this normal with new sand? Last year when I backwashed, it was always dirty green water.
Is my filter working? It seems like I have to back was every 10-15 minutes due to pressure but the water isn't as dirt as I thought it would be.
Today the water is blueish with some algae that I need to vaccum.
