If you are using a liquid glue, which that looks like it is, I would recommend turning off all flow before you start working.
When I switched over to a "real" coral gel glue, I stopped having this problem, but a lot of flow, will just whip the glue off the coral, or all over it (killing it), or just beat it into the tank. (You will notice this four hours later when the surface of your tank has a thin superglue layer...its like a crust.)
Thats why I feel that its worth it to buy the aquarium gel stuff. No problems, meant for aquaria...more glue for about the same amount of money. Just put some in your next order from fosters or marinedepot.com
