Our weighted 3.5-inch sponge filters are a great addition to any aquarium! We really recommend these filters in aquariums with small fish or shrimp due to their nature and the fact that they won't suck up small fish or shrimp. We use these in our guppy breeding aquariums to filter water and waste while keeping fry safe!
This filter is great for 10-20 Gallon aquariums but can be used in larger aquariums as long as adequate airflow is provided and a set up of multiple filters.
An air pump is still required to have our filter work.
Temperature below 20° f or above 90° f do not fall under our DOA Policy, and you may not be refunded a full amount
