So now that we have added alcohol to the thread, maybe I should go through one more demo again:
So here is new frag (darth maul porites) in the bag:
Frag on original plug (possibly crawling with all kinds of terrible pests, this frag came from an sps tank from LFS)
Got to chisel the frag off:
Yes, some of the frag remains on old plug but less likely to bring in eggs by removing old plug
Frag sitting in about 4 ounces of saltwater (either tank water or from bag)
Ten ml's of Bayer as pictured (make sure you use the Bayer I showed, not some other version)
While the frag soaks for 5 (five) minutes, get out new plug and glue
After the 5 minutes are up, the Frag is sitting in fresh tank water and ready to be glued (remember, Bayer is toxic so do not use your fingers in it, don't smell it, don't spill it and don't drink it--it is extremely hazardous. Notice on the far right are tweezers for handling frag)
Frag is now glued on to new plug
Glued on new plug and sitting in fresh tank water so the glue will harden.
