CORRECTION to my previous post ...

1. most SNAIL killing chemicals contain copper, arsenic, or cyanide.
2. most ALGAE killing chemicals contain herbicides, which are also toxic to
fish.

Same results if you use too much though, nearly everything in the tank dies.

I recommend you use strong chemicals like these only as a last resort, and
only if you are sure you know what you are doing.

Yes, all of these are toxic to fish too.
