I'm new. I looked around various forums and topics but didn't see this listed anywhere. My pool cage has new 20x20 (squares per inch) on the upper levels. It has 14x18 (normal screen) on the sides and heavy 14x18 on the bottom (also called pet screen). My pool is always cooler than the neighbor's (no pool cage) by 2-4 degrees. I'm curious if the finer screen will noticeably slow down the sun burning up FC?
