Yes, Santa Monica, you were correct. More screen layers and roughing them up is more efficiant. (Is there a spell check here??)

I posted this morning, but I took the pictures and did the changes Thursday. Then I had like nothing on the either screen. From Thursday to this morning, I had a thin spotty covering on the Triple Screen. I was not sure if the build up was from the debri in the water getting trapped between the screens or was it growing. This morning after I posted, I cleaned the Triple Screen and then sewed a line at the top to keep the gap closed between the screens. I was gone most of the day. When I came home, I noticed it had more growth.

I will get some pictures.
