Snail Remover Tabs are a popular, copper-free aquarium treatment designed to safely eliminate up to 90% of pest snails (like bladder, ramshorn, and pond snails) within 72 hours

. Because they are formulated without copper, they are safe for most freshwater fish, shrimp, and live aquatic plants.
 
  The 3-Day Treatment Timeline
Day 1: After adding the tabs, irritated pest snails will begin crawling up to the water's surface.
Day 2: Snails become sluggish, less active, and easy to manually remove.
Day 3: Most snails will be gone. Perform a mandatory 50% water change to clear out decomposing organic matter.
