yes, make a thick paste of the kalk mix and squirt it right into them. If you have a lot of palys, its tough to do though, especially if they are in crevices in the rock. I use an old salifert syringe and just cut it a little so the opening is thicker. Just be careful of any corals that may be below the palys your trying to inject, some kalk will probably fall and can burn/kill whats below it
