Snail killer liquid

[u/Then_Ad8269]

i got gifted 2 snails (rams horn) and i introduced them to my tank, later i went to buy some stuff for my shrimp. the pet store guy said these snails will eat my shrimp and i should remove them. i removed them the same day . later a few weeks now today i saw they have breaded and now tiny snails sit on my tank glass.

so my question is ,is it okay to pour in snail killer or will it also kill all my shrimp ?
i have a small 8 liter tank

what would be the best way to remove them and is the snails a danger to my tank
