“Worked well in one of my tanks but the main reason I bought it was for my shrimp tank. Checked it after an hour and yes it worked for snails well but caught more shrimp. If I hadn't have checked it I'm pretty sure I would have lost a lot of Shrimp. Please mark as 'not suitable for shrimp tank'. Other than that it does its job well.”
“An interesting gizmo that actually works. Set it up before you go to bed, place it in your tank and remove it before the sun comes up the next day. Easy. The only con is that really small snails can still escape.”
