Well, looky there! So pretty!
Taking down the bucket requires some skill and caution. If you have the ability to drain it out the backside - do that first. You don't want to undo all your hard work!
Might want to check your return hose too - sometimes the iron gets accumulated in there and can gush some water back into the pool even after you think you've filtered it all out. I would give everything a solid rinse like Pat said above - filter carts, strainer baskets... anywhere that iron touched it's going to flush back into your pool when you take the bucket down.
This is ALL NORMAL - just part of the cycling to get it out of the pool!
How's the chems looking? Are you holding up on your FC, PH?
