Yeah, you're on it now. Good job. I figured it may a little early for the OCLT, but at least your water does look much better from those pics. Algae is a funny thing because it's not always green and visible. Keep at it and when you get back home add some more bleach, and don't forget to do all the other things you see listed on the SLAM page, especially the brushing. You're gonna win this thing now I'm sure. Just be patient. Have a good one.
