AQUANEAT 12-Pack Pre-Filter Sponge for Aquarium Shrimp Fry Fish Tank Filter 0.8 inch Intake, Replacement Foam Cover

Features

• The information below is per-pack only
• Dimension: 8x4.5cm/3.2 x1.8, the inside hole diameter is 2cm/0.8; for a snug fit, check the size you need carefully before placing an order. The sponge's inner diameter accommodates filter intake within 0.8-1 inches (2025.4 mm) due to its elastic properties.
• Lifesaver: Keeps baby fish, 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: 6 pcs of pre-filter sponge (Note: The hole doesn't go all the way through the sponge. They come flattened in a vacuum bag; just unpack and rinse them and these sponge filters will puff up to normal shape and size.)
