So my water is near perfect, no odor crystal clear. But every day I see a cloudy green collection of foam in the back of the filter bucket, where the water circles down from the surface towards the filter. I've just been scooping it out with a scimmer and wiping the back of the wall.
It's a 500 gallon tub, CH 180, TA 60, PH stable between 7.5-7.8. Using bleach sanitizer with CYA at 50 ppm. Tub is used 3-5 times a week.
Only other relevant details are, I just got new filters which seem to have much less flow resistance than the older filters.
I'd like to know what's causing the foam and is it a problem?
