Congrats on a successful reflow.
I float and bop 
Floating is desirable, it means there’s enough solder.
Watch Vesture’s video from about 6:20 for a couple of minutes for a good demonstration. He ‘bops’ out the excess solder around 8:10, this works better with larger, heavier LEDs but is trickier with smaller, lighter LEDs.
(Obvs you can watch the whole thing, there’s good info in there showing different heating methods.)

I use a cotton bud or a little piece of soft wood for bopping but fingers and tweezers obvs work too.
