Aquarium Double Sponge Filter, Comes with 2 Spare Sponges (S)

I just ordered my second one to replace my other outside of tank filter. I LOVE this unit. Super quiet, easy to install and the fish don't even notice. Highly recommend

Used for a shrimp tank. Have some other Hygger products such as lights and wave makers. All have been working without issues for 3 years running.

This review includes tips for the extra sponges!!! I have had 3 of these for over a year and highly recommend them. I have all size smalls and use them on 5 gal, 8gal, 10gal tanks filled with mostly shrimp and snails and a few fish. They work great and they require little to no maintenance. They easily come apart if you do need to clean or maintain and there are no moving pieces to worry about breaking with wear and tear. They come with the bio balls and an extra set of sponges. They don't require a lot of air, so I'm able to use a splitter on each air pump to also power bubblers. They are completely quiet depending on what level you place the output spout compared to water level. Shrimp and snails love them because they are safe havens to rest on full of yummy things to eat. They cause little to no motion of the water if you have inhabitants that like things calm. And they there is zero risk of having a filter accidentally suck up a baby of any species. The black sponge blends in well with the background and the only part that actually sticks up and shows out of the tank is the tiny clear airline hose. In over a year. I've yet to come anywhere close to needing to replace the sponges, however they have come in handy: 1. When cycling a new aquarium, I bought another of these and swapped out one of the towers (balls and foam) from an existing aquarium with a new one. I did this with two different tanks. This had little to no impact on the established tanks since I only took half of the filter media. It got the new tank to cycle almost immediately. 2. To keep from vacuuming up tiny fish fry during water changes, I use one of the spare sponges on the end of the siphon hose (1/2"). It won't suction up debris with it on, but it works great for water changes in a heavily planted tank where I let the plants handle the debris. 3. (Sort of a spin off of 1 and 2). If you have multiple tanks and are worried about cross contamination, store one of the extra sponges in the back of the tank. Use this if you need to spin off an emergency bin for any reason, and/or when changing water on that specific tank.

It has really kept my oriental fish bowl clean.

Love these sponge filters. Easy to clean and replace. Just make sure you get proper size as medium is just a little too big if you have the small filter.
