I also noticed an increase in foaming around the waterfall area. That's why I'm very interested in either a shower filter or one of the clarity units. It seems to be worse when the ambient temp is several degress +/- the pond temp. Right now, water is warming slightly and nighttime temps are finally started to warm as well. This has reduced the foam by 80-90%. For me, it seems to be a seasonal effect. I know, it's still caused by DOCs/TDS. Thats why I want to know which would be the best route to go before adding something and wasting my time.
Don, I too am anxious. HURRY UP DAMN IT!!
