Hi there...sorry you waited for me but its just as well because you reported dramatically increasing clarity.
(And yes, it was quite a party...dispatched the very last guest a few hours ago (yes, late Sat. afternoon from a Frday night party
and tore down the soundstage. Some swam til dawn. All I can say is what a night!)
In my cold water slam, I'd been able to actually pass the Overnight Chlorine Loss Test without getting the drifts of debris off the floor, then turning off the pump overnight, then doing a slow vac. BUT you're dealing with summer temps so perhaps a slightly different aproach will work for you.
If your FC is topped up and mixed in for the night, why not turn the pump off tonight to see if more settles.
Then in am, turn on filter, top up FC, then using the vac, veeeeerrrrrrry slowly (think tai chi) "approach" the edge of each debris pile and gently move over it....pretend you're decommissioning a bomb
Don't worry about the edges where the side meets the floor. Get it on a later pass when visibility improves and theres less for the filter to deal with. Don't get in the pool...too much wave action.
Be prepared for possible pump basket clogs where you'll need to shut down, clean out the basket, re-lube or wet the o-ring, re-prime and then switch to waste again.
Its entirely possible that the stuff on the floor has just collected through the "top layer filtering" you've been doing, which was actually the idea --- getting the debris to settle and getting enough clarity to vac to waste.
While there are other ways to get stuff to drop to the floor, they can be complicated with unintended results and don't work right if there's still active algae so they aren't recommended by TFP.
As to length of your Slam...again, I was lucky in that my 12 days were in cool weather and cold water. Its not uncommon to see summer slams run 3 weeks or more.
My sense is that based on your pace you'd be able to see the deep end in another week to do a slow vac there. So the shallow end vac might be good practice
