Hi, We had a dust storm blow through the Phoenix valley last night. My Waterfall ATS is outside on my 140 gal. freshwater mini-pond. I had to turn off the pump in case the wind knocked over the waterfall and it emptied my tank. The screens (I have a split screen so I can clean one at a time) dried out. Should I now clean them? I turned the pump on again this morning and the algae on the screens is looking a little sorry. This WFATS keeps that tank in great shape.
Thanks, Tony
