Well, I did not notice as to how the chlorine was diluted ie how many parts
of water to one part of chlorine.
I have tried dipping plants for 30 minutes (!!) without any mass of goo.
Frankly, I didn't intend for that length of time, but was too busy preparing
other stuff. All 27 species were ok. Snails went dead, so does the eggs.
The bottom point here is, even if you dip it for 2 minutes, it will die if
the chlorine was not diluted enough. BEWARE !!
