Well, someone spoke to me about trap door snails. My pond
is a 70
gallon baby and i am unsure if ping pong ball sized snails
would wipe
out all the plants or just the excess algae.

It's my understanding the Japanese trapdoor snails
don't eat plants, they do eat algae, and since they're
livebearers they don't reproduce that often. I started
with maybe a dozen two years ago and after a
search of 3 ponds today, I *think* I found one!

OR, if this would be too
small for them. I had some little black snails and that's
about all i
know.

I don't know either.
