If there is ANY glue left on the plants when you finally add them then the factor may be how big your tank it. If it's only a 2.5 gal
tank then it could be a problem. Again that is assuming there is still any sealant left. But if they are being added to a 125 gal
(for example) do a large water change the next day to be safe and you should be good to go.
If you do every step you just described, though, you will probably be okay regardless. Just make sure you get it all off . . . obviously . . .
Telling you something you already know there.
Hopefully some others will sound off soon. Maybe someone will know about removing that sealant better or if can even be done completely.
