SunGrow 10-Gallon Betta Sponge Filter, Underwater Center Aquarium Filter, Attach it to Air Pump (Not Included) to Run, Works for Tropical Fish & Breeder Aquarium, Perfect for Fry & Small Fish

I love these little betta sponge filters. They are easy to clean, costs less than a normal overflow filter and look great in the tank. They are also less noisy. You have to have an air pump for it, but I always have an extra one laying around. Also, with these type of filters, they give oxygen to your tank. The filter I got was small, so make sure you get the right size that will meet the gallons of water in your tank. These are especially good when you have nano fish, fry and shrimp. My shrimp love these filters and are always hanging out on them. Great Purchase!

This little filter keeps my betta fish tank clean. Love that its small and still cleans.

I got a betta fish for my class pet and our first fish got sucked up into the filter and died after a week of having it. I got a second fish and everyone told me that the betta doesn't need a filter, but I felt more comfortable having one so I did some research and found this filter! It's great because it bubbles and adds oxygen to my water and it keeps the tank somewhat clean. It has been a great purchase and I am so glad that I found this. It's not going to keep the tank clean like a bigger filter, but it definitely helps. Thank you so much!

This filter is a go to for a fish that needs oxygenated waters and soft flow and it provides nice filtration to make a dirty tank clear in matter of time.

The filter part of thos is useless. Works great as a bubbler, but that's it. Too big for a small betta tank as well.

Fish tank works great

worked nicely , but I upgraded to a bigger aquarium set up , now it is in holding for future needs

I wanted to love this bubbler more, but it’s pretty loud for the size. I have a different bubbler that’s bigger and you can’t hear it as much as this one.

il me fallait un tout petit exhausteur pour mon 12l il est parfait je recommande

Sto cercando un filtro per il mio piccolo acquario, e ho optato per questo. Nell'annuncio non viene descritto che mancano pezzi per far funzionare il tutto. Annuncio tradotto male e inutilizzabile da solo. Per non farci mancare niente la scatola (del prodotto non quella di amazon) era aperta... Io non so come lavorate... Sotto zero stelle

Great for our little 20l tank in our classroom keeps our one little fish very happy and clean. I added an air pump to give it alittle extra kick but it does good job on its own. Would definitely work great for the little single beta tanks

Im using this on 20x10x20size tank for betta. Compact n workin well! Thanks a lot

This was shipped super fast. Got it yesterday and put it my 5 gallon tank for my 2 betta fish. It was so easy to install. Perfect size, it doesn't take up too much room. It's actually keeping the water crystal clear. I didn't want anything bulky in the tank and these were just the perfect size. I can control how much bubbles it disperses, which is great because my bettas don't like too much bubbles...it stresses them out. My bettas love it. I'll have to get more for my 10 gallon tank at home.
