You can buy syringes at any drugstore. I am diabetic and have traveled
through to many places. You can always buy diabetic supplies. There
are no restrictions whatsoever. Most drugstores will sell you a small
package of 10 syringes for a couple of bucks. You can use the
alkalinity solution from a two part buffer like B-Ionic and inject that.
I have been told that works. I will be trying this on the weekend as I
now have a growing aiptasia problem.
