Aquarium Pre-Filter Sponges for Shrimp, Fry, and Fish

The filter intake sponge cover is a great baby fish saver designed to protect 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. 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 pieces of pre-filter sponge, with a dimension of 8x4.5cm/3.2" x1.8" and an inside hole diameter of 2cm/0.8". It is important to check the size you need carefully before placing an order to ensure a snug fit.

This sponge is a lifesaver, as it keeps baby fish, shrimp, and snails from getting sucked into HOB filters, power heads, or canister filters by simply putting a piece of the pre-filter sponge over the intake. It 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 holds up well to being rinsed and reused, and it allows for great water flow. The package includes 6 pieces of pre-filter sponge, but it's important to note that the hole doesn't go all the way through the sponge.
