Since everyone has their own method (using medicine with copper in it for example or bleach), what is your method and how effective has it been this far?
I tend to dip the plants a few times in vinegar and a light copper solution (as copper kills snails and most invertebrates). Then I rinse them throughly in water to make sure the copper treatment is gone so it’s safe for my tanks that do have invertebrates and snails (the ones that I do want that is).
