-Anti-scratch scratching board AND cat bed in one Seachem - Tidal Zeolite

Naturally occurring mineral that binds together toxic ammonia and heavy metals through an effective ion exchange mechanism ensuring the tank is as clean and healthy as possible for your aquatic inhabitants. The highly porous material is the highest ammonia binding capacity of an available zeolite, and is ten times higher than certain products and twice the capacity of the nearest competitor. The fish safe Seachem Tidal 35 Zeolite won't deplete calcium in saltwater and it won't increase general hardness in freshwater environments, where the ionic strength is often quite low.
