[Why Does My Solar Cover Do Nothing?]

We purchased a solar cover this spring from In The Swim; they offered 3 styles and we went for the "middle of the road" in price (silver not blue).

We must be doing something wrong (bubbles side down, correct?)....or bought the wrong item (won't be the first time). The covers are touted to be able to raise the temp 10-15 degrees. Our thermometer will show an increase in temp, but as soon as the water is circulating within minutes drops right back to what it was before the solar cover was put on. It appears to be heating the top layer, maybe 6 inches, of the pool surface. We have left it on for days with virtually no change. We were kind of hoping to extend the swimming season here in northern NJ.....

Thanks....Al

[Cleaning Hayward Ec-65 De Filter]

I need to remove and clean the Flex-tube filter assembly, which the owner's manual says to do yearly but gives no procedure. Is it just a matter of removing the 20-odd screws and the whole assembly lifts out? Or is it more complicated than that?
