Sera Hard Aquarium Sponge x2 Pack

Sera Hard Aquarium Sponge x2 Pack

Occasionally, the view on the underwater landscape and its inhabitants can be obstructed. If the aquarium glass is covered with algae or a biofilm, this is generally not a problem for the animals, but it is of course unpleasant for the observer. Spot algae can often only be removed with great pressure. Water stains and slight lime marks are also an annoying problem, especially in open aquariums.

The Sponge Hard is designed precisely for these kinds of dirt. The top is made of fine, woven steel wool and cleans the glass without scratching it. The aquarium can be cleaned quickly and easily right into the corners with low pressure.

• cleaning sponge with woven steel wool coating on one side
• also removes persistent spot algae and lime marks
• soft support material for removing biofilm and thin periphyton layers
• ideal for glass and other hard, smooth surfaces
• in a practical twin pack
