AQUANEAT 6-Pack Pre-Filter Sponge for Aquarium Shrimp, Fry, Fish

The filter intake sponge cover is a great baby fish saver, designed to protect your lovely little aquarium critters from being sucked into the filter. This pre-filter sponge can also be used to dampen the outflow, making 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 the filters.

This prefilter sponge provides both mechanical and bio filtration, and 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. The package includes 6 pcs of prefilter sponge, with each sponge measuring 8x4.5cm/3.2" x1.8", and the inside hole diameter is 2cm/0.8". It is important to check the size carefully before placing an order to ensure a snug fit.

The filter intake sponge cover is a lifesaver, keeping 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. It also does a great job in catching flake fish foods, plants, and any other large particles floating in the water, keeping the tank cleaner and extending the time between cleanings.

The material of the sponge roll holds up well to being rinsed and reused, allowing for great water flow. The package includes 6 pcs of pre-filter sponge, but it's important to note that the hole does not go all the way through the sponge.
