Product Description

The filter intake sponge cover is a great baby fish saver that protects your lovely little aquarium critters from being sucked in. This pre-filter sponge can also be used to dampen the outflow and make the water more stable for your betta. The cylinder sponge foam prolongs the life of the pump unit and boosts mechanical filtration by keeping solid waste from getting into filters.

Key Features

• The pre-filter sponge provides both mechanical and bio filtration.
• It is recommended to rinse the sponge roll periodically based on the bio load of your aquarium tank, as it will get dirty over time and may restrict the water flow of the filter.
• Package includes 6 pieces of pre-filter sponge.

Product Details

• Dimension: 8×4.5cm/3.2” x1.8”, with an inside hole diameter of 2cm/0.8”. The sponge’s inner diameter accommodates filter intake within 0.69-1.15 inches (17.7–29.2 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 piece 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 lasting 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.

Package Includes

• 6 pieces of pre-filter sponge. Note that 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.
