Clearing Clumps not Falling

[fledavid]

I am doing the Kenridge classic pinot noir kit and have been at the clearing stage for a week. I've followed all of the instructions, adding the kieselsol, then degassing 8 times over 2 days, then adding chitosan and mixing. It says to wait 6 days for it to clear. Straight away clumps formed at the bottom, however over the week some have formed and stayed in the middle of the bucket. Anyone have any experience with this or how to get these clumps to lower so I can rack it off?

I've left it outside in my hut over night, however still no movement. Even shaking the bucket the white marks/clumps don't move

I'm not sure if this will help you, but once I've put in my clearing agents into my carboy, about 2 days later or so, I give my carboy a quick twist back and forth so that sediment that is clinging to the glass can fall to the bottom. I wouldn't call the sediment I get on the walls of the carboy 'clumps', much closer to light sand, but it is very visible before it is dislodged.
