AQUANEAT Aquarium Air Powered Sponge Filter, Fish Tank Bio Bubble Filter with Airline Tubing, Valves, Suction Cup(up to 10Gal)

I'm still leaning how to setup and maintain a fish tank with multiple fish, I've only ever had beta fish. I'm also learning about the different accessories needed. So far this product is working great from what I can tell. It's a good size for our 10 gallon tank.

Wow! I just got this today and I can honestly say without hooking it up that this is going to be a really good filter! It’s sturdy, heavy and is durable! I bought the one pack and I’m going to put this in my tank for a couple of days to see how it goes but I love it right now and I’m sure my betta fish will also!This is a must buy for such a good price!UPDATE: Added it to my 10 gallon tank and it cleared up the water within an hour and the water has been crystal clear ever since!!! I ended up buying the four pack from them a couple of days ago to use in my other tanks and they are a little smaller then the singular 10 gallon one but they are the perfect size as to not take up a lot of room in a ten gallon. In a five gallon it may seem a little big but that’s perfect because you know it’ll filter out the water without leaving it cloudy because it’s small. THIS IS A MUST HAVE IF YOU ARE PLANNING ON GETTING MORE THEN ONE FISH IN SEPARATE TANKS!!!! I’ll be coming back for more in the future

Great sponge filters and easy to modify with the air stone. Have these in both of my 5 gallon betta tanks. Overall, good find!

So it performs really well in my opinion. I use it to add air and some sort of filtration to a 40 gallon trough. I've had this item now for about 5 years now, cleaning and changing the sponge every so often. And it still works as it did the first year I have had it. If you want to change the size you could make it longer or smaller depending on how many middle piece you want to add or take out. I have one that is about 8 inches tall and another about 4 inches tall. It has a nice weight to it and never had an issue with it floating up and away.

This was the perfect size sponge filter for my 5 gallon, and I'm sure it would work for my 10 as well. I did, however, need to add an air stone because my Betta didn't appreciate the big bubbles this produced. I watched a video and modified this to have a small air stone and it now produces perfect bubbles. The second, more important issue I had was the shape of the sponge. It is widely ribbed, and I had it in the corner against the side. My little Betta wedged herself, nose down, in one of those ribs. Thankfully, I found her in time and she's okay. So it now sits awkwardly away from the sides.

I was afraid of my betta being harmed by a standard filter and the water flow isn’t ideal for a betta. This filter works like a charm and it’s fairly easy to clean with a plastic blade. I clean it out with dechlorinated, clean water during my biweekly water changes.

So much better than other filter styles. So easy to clean! Reusable!

Super easy to clean in tank water from the water changes. To ensure you don't muck up the tank with all of the debris this thing sucks up, I recommend slipping a plastic bag over it to get tank water, squeeze it in the bag to clean it, never rinse it under the tap. Only clean it with tank water. The tank is healthy, and looks great and has been established for a while now. Great air powered filter for the money. I use this along with a small tabletop canister, from sun sun and another smaller 2 sponge filter on a 30 gallon freshwater planted tank. I got these to increase air exchange with the bubbles, and the 2 sponge filter to increase flow because tbh my plants grow super fast and I suck at trimming in a timely fashion. When I clean this filter in used tank water I squeeze it til the water is chocolate brown and then I just stick it right back on the filter base.
