I have noticed that Had-a-snail is also copper-sulphate. Is it also true
that this product at the recommended dosage would damage Valisneria?
It would seem that the yellow spots/holes that I observed may not be caused
by the snails but by a shortage of Potassium (presumably it was all used up
by the rapid growth) and that they are in fact beneficial algae eaters.
Curious if anybody else has any opinions pro or con snails. Probably most
people avoid them for aesthetic reasons. I used to have a couple of large
ones that were quite interesting to watch.
