I've been a pool owner for the last 3 years since we moved into our new house. During that time I've been performing normal procedures to keep it clean with good results. Recently this has changed and I'm thinking I've got a problem now with my sand filter. The main issue has been that the water is staying cloudy for the most part and I don't really see any rise in pressure over a period of time on the filter like I used to. This has been going on for the last couple of weeks.
Now I tried to do a normal vacuuming through the skimmer and after cleaning about half the pool, I noticed that I had the debris from the bottom being returned back out into the pool which of course turned it all cloudy again.
The pool filter and sand were installed brand new 3 years ago when we moved in. We do run the pump a lot (my wife likes the waterfall on at all times) so I thought perhaps it was just time to change the sand, but I am not sure about it since I am not seeing a rise in pressure.
I've also been reading about channeling effects which might explain the debris shooting right back out into the pool without being filtered. I didn't see any recommended procedures though if that is the problem.
Can you experienced folks out there help me out on what to do?
