Hygger Aquarium Double Sponge Filter - Ideal for Freshwater and Saltwater Fish Tanks

Emily: Was looking for a filter I could sanitize instead of buying cartridges and just throwing them out afterwards. This is the perfect solution. At first, I was not sure it was filtering using the sponges but surely after a couple of days I can see a small amount of material building. My only complaint is that I do not think it puts as much O2 in the water as a normal filter but that may be due to my pump size. This was a simple fix bc I had an extra airstone and pump anyway. I am purchasing another because I think this will be PERFECT for my beta tank. Mine did come with the extra sponges and both suction cups. It will be 5 star for my beta tank but I'm giving it four due to the 02 levels falling in my 29 gal community tank.

92 Aggie: Needed something for a 5 gallon shrimp tank and thought I'd give this a try. The design looked real good so I made the purchase and installed. I was mildly blown away! Now a lot of credit needs to go to the air pump which is a fantastic Eheim 200, but this little filter works like a champ. It has an amazing amount of water circulation and works really well even when the water level is down. This is money well spent.

Brenda Lee: Mine keep getting space where they connect which allows the air to escape and then the filter isn’t working properly

Carrie: 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...

Ares: Looks cool, good material, comes with bio balls and back up sponges, the most important thing is the noise from the bubbles from the outlet is well controlled. Well done Hygger, hope bigger size can be produced more.

Push: I wanted to write this review to address the most common complaints I saw when looking for a new sponge filter.

1. "The replacement sponges were not included." The replacement sponges come squashed into the bio media compartments and you must disassemble the filter and remove them (which you should have noticed if you had bothered using the bio media).

2. "It made my water cloudy." Rule #1 of aquariums, RINSE EVERYTHING FIRST, the bio balls are covered in dust generated from rubbing against each other for however long they've been in the packaging.

3. "Not enough suction power." In many cases see point 1, its the same people who couldn't find their replacement sponges, and pretty self explanatory why that would cause issues. For everyone else, you need an air pump powerful enough to create the lift required to generate flow. A ~3v is good enough for the small, and a 4v for the medium. A 2.9v whisper quiet generates enough flow to piss off my betta if I don't regulate it.

4. "It stops working after a couple weeks" These are higher quality lower micron sponges, not your cheap drive a car through the gaps sponge filters of the early 00's. They will clog...

bobbiebobbie: The media could not be loaded.  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

Godfrey: I gave it one star because it still works in my aquarium and my first Hygger Aquarium Double Sponge Filter 10-40 gallon one I love it easy maintenance and install, but this second one I bought the bigger version 15-55 gallon came to me incomplete, without the two suction cops, ceramic media balls and the two media container.

I advice you to look else where
