More DE?

I think due to my FC being around 2ppm after the weekend, algae has started to appear on the floor and walls. The last two (2) evenings I have brushed the floor and walls then added 6% bleach in an attempt to raise FC while battling the start of algae. My CC has been around 1ppm and FC has decreased a little overnight so it seems I have a few more days of shock level (CYA is around 50 so using Ben's chart shock level would be 15ppm) to get CC less than .5ppm. My water is still clear.

I plan on vaccuuming after work followed by another evening round of brushing and bleaching. Any suggestions on how to clear the floor and walls?

Looks like you do have a little ways to go before you can let it drift back down. Keep it at shock level, brush after your chlorine additions, keep pump/filter running, cleaning filter as pressure indicates....it will clear up but will take some persistence.
