Hello, we've had our brand new pool open and in use for about a month now and I've noticed that the Hayward Swimclear Cardridge Filter seems to have low PSI all of a sudden. It's hovering around the 2-4 range when our Hayward Ecostar variable speed pump is running 1380RPM. If I recall correctly it was averaging 15PSI when the pool was first opened and equipment hooked up.
I've had to vacuum some topsoil and worms from the bottom of the pool a few times recently as we're doing some landscaping around it and the wind swept it in. Could anything like that be causing the low PSI? Is this something to worry about or is it better than having high PSI?
The pool is only 14' x 25' with a 7' deep end of that helps at all. Water is also crystal clear. Chlorine is a bit high but everything else is reading regular.
Thanks in advance
