Household nano sponge

Description

• Dimension: 5.91?? x 3.35?? (150mm x 85mm), the inside hole diameter is 1.18?? (30mm); for a snug fit, check the size you need carefully before placing an order.
• Lifesaver: Keeps baby fish / fry, shrimp, and snails from getting sucked into hob filters, power heads or canister filters by simply putting a pc of this pre-filter sponge over the intake.
• Improve Filtration: Does a good job in catching flake fish foods, plants and any other large particles floating in the water keeping the tank cleaner and last longer between cleanings.
• Maintenance: Rinse the sponge roll periodically based on the bio load of your aquarium tank. The material holds up well to being rinsed and reused and allows great water flow.
• Includes: 2 pcs of pre-filter sponge (Note: The hole doesn’t go all the way through the sponge.)
