Things MIGHT be turning my way. My CC level is staying at 0.5 ppm or zero. My chlorine loss overnight is declining (only about 4 ppm last night). Then, today when I backwashed the filter, I noticed quite a bit of white...something being pushed out. Is that what the dead algae would look like?

Also, from my experiments last night, the glass with the dichlor added is almost clear, while the one that I didn't put anything in looks the same cloudy/hazy as before.
