I added floc to my pool, didn't follow the instructions properly and now what was just a small cloudy issue has become a disaster. Luckily, my water is balanced and clear on top but there is still leftover floc on the bottom and walls of the pool but water level is too low so I cannot vacuum to waste until Saturday when water is scheduled for delivery so should I keep pump turned off or let it run since floc is already in the filter sand? I also bought new sand and plan to replace sand tomorrow or on Saturday, but after I remove the old sand, deep clean the filter and then add the new sand what do I need to do to make sure my new sand is not contaminated with the remaining floc in the pool?

Do you have a multiport valve? If so, place it on recirculate to bypass the filter. At least that way you can keep water moving.

I wouldn't add the new sand until you are confident you have removed all the floc. Might as well gum-up the old stuff after you've exhausted all the filter-to-waste options. Once you think you're clear of all the floc, then change the sand.
Yes, I do have a multi-port valve. Great idea to put on recirculate to keep the water moving but keep from going thru the sand filter and putting back into the pool.Welcome to TFP!
Thanks!
You'll waste a lot of water but "vacuum to waste" will safely get rid of the floc on your pool floor.......most of it, anyway.
