To scoop the foam or to not scoop the foam when SLAMMING?

When doing my weekly SLAM of the tub (chlorine to ~15ppm and a couple ounces of the oxidizing sanitizer), a lot of foam is generated. Should I be scooping that foam out or are there still "active" chemicals in there that have more work to do and I should leave it alone and let the filter do its job?

Thanks!
