How do I prime my vacuum when it comes time to remove flocculated dirt from the bottom of my pool

[poolFACTOR]

hi,I recently moved into a home with a pool of 30,000 gallons, I’ve done my fair share of research bought all the chemicals and so forth, I superclorinated the pool when I first moved in with about 25 gallons of liquid chlorine which killed the algae in the pool And turn it from dark green to a navy blue, I excessively brushed and manually vacuumed my pool but the water remained very murky, i waited till my chlorine levels drop to nearly 0 and balanced my ph and alkalinity then added about 3 pounds of shock to raise my chlorine levels back to 2-3ppm tonight, I will be adding flocculent in the morning to combat the murky water but I noticed every time I would vacuum I’d stick the end of my vacuum hose in the return jet to remove the air inside it, my question is with the pump off when I let the flocc sit for the day how do I remove the air from the vacuum so I will get good suction when time comes to vacuum to waste, will the return jets run when set to waste? Will the air bubbles from the vacuum kick up the dirt if I try to prime it that way?, I don’t want to mess this up when I add the flocculent so please help me out, I will be using cloroxx brand sink to clear for my flocculent of choice.

I am not a fan of floc. It is a "when all else fails" thing for me. 

Lower vac head and hose into deep end slowly, then manually feed hose into water after it a few feet at a time until the hose is completely underwater. Wait a while for any stirred debris to settle then start pump and insert vac hose through skimmer door and into port.

Update:my pool is 30,000 gallons, I added 24oz per recommendation of the label, went to bed, I woke up 12 hours later to find that the shallow end of my pool was now clear that I could see the bottom well, but the deep end of my pool went from milky to hazy and I could barely see the bottom, i wait another 6 hours check again and it looks the same. I don’t know if the flocculant has worked to its fullest potential yet, my question is should I wait till the morning vacuum it out and pour another bottle or should I add the bottle now on top of the flock I had added 18 hours ago.
