Depends on the drip. You can set it from a steady dribble to an occasional drip by pinching an airline tube or running it through a valve. Also depends on the size of the container and starting water. Less starting water and a smaller container is going to fill to your new tank water faster than a larger container. Usually you can get something in the tank within 30-40mins. Sometimes you might spend a couple hours. Occasionally people buy something very expensive and spend all day converting it. This is actually a temporary tank to let them adjust to an inbetween and then get moved on. I tend to lose male guppies and experimenting with feeders I found running extra hard water with a level of salt kept the feeder guppies and feeder ghost shrimp alive much better before moving them to my normal water. That in mind the tank is not aquascaped at all. It's just everything thrown in there to give the shrimp hiding places. Bare adjustment and quarantine tanks may be convenient but they'll kill more fish and inverts. The crayfish we just mix 50/50 old to new water, wait 10-20mins, and plop them in.
Blue, jade, and striped applesnails and pink ramshorns
Look very closely for cherry shrimp and some malaysian trumpet snails
My trio of blue swordtail guppies
The crayfish were in a 40g breeder but water was found pooling outside a corner. It was drained, inspected, refilled slowly, and nothing so the crayfish are mostly in the 30g long. I pulled out the blue male who was harassing everything back to the 40g so there is a blue female, a wild color male which is red, red female, and orange female
Red trying to ambush fish
The blue male in breeding morph, crayfish have 2 forms that they will switch between seasonally
I also have small wild crayfish in 2 tanks with one having my orange/red striped guppies
Then I have a 40g orange spotted sunfish tank and a blue ramshorn 10g
