I'll let someone else talk to you about your filter but I am just wondering, why are you floccing the pool this weekend? That is something that we seldom recommend. Maybe give us some current water testing numbers taken with a drops based kit, tell us what type and size your pool is and tell us what problem you are having. Someone here can take a look and see if floccing is the way to go for the situation you have there.

EDIT -- Also tell us exactly what all -- meaning ingredients --- you have put in the pool.
