What can I drop inside a tank to kill all invertebrates?
I have a small tank that has some scuds, cherries and snails. It's pretty much been in my loft forever and things are breeding out of control. I would like to turn this tank into an all moss tank so I need everything out of there 100%. Obviously, netting things out is a giant waste of time and you can never get everything 100%.
Can I just drop something in the tank that would kill all shrimp/snails except plants and fish? I'll have all day to waste on this so maybe there is something I can pick up from a store? I did see some liquid medicine that gets rid of snails but not sure whether that is fish/plant safe.
Thanks for your help.
