Blue Planet Snail Rid 125mL
Very effective and got rid of the snails in my tank. Did take a few uses but they've all disappeared pretty quickly! I've bought a few bottles of this because I go through it quickly but there is definitely noticeable results. I'm about to get more plants for my tank which means snails so you know what I'll be using!
I have a 37 and a 125 gallon aquariums and they both are still loaded with snails.
