AQUANEAT X-Large Bio Sponge Filter - Perfect for Breeding Fry Fish in Aquarium Tanks

DrJohnsonCom: Best. Filters. Ever. They don't suck up baby fish. They can be eyeballed for "clean" and they're pretty easy to get out of the tank to clean. A plecostomus will keep them clean and a lot of other fish will pick copepods, rotifers and nematodes off these. They're pretty quiet (only the air pump contributes noise) and a Tetra Whisper is nice and quiet They have a airstone in the box and it's "pretty good" but a glass bead should be its replacement later. These sponges last for years upon years. I use one of these in tanks as small as 30-40 gallons and that "overkill" results in water that is GIN CLEAR and fish do well. I'll drop two of them with "pretty stout" airflow in a 300 and it works great. Finally, you should be aware that with some really basic parts from home depot, you can engineer an aquarium water powerhead onto these and drive their output to new heights and ridiculous water clarity. They can be "cycled" quickly with a hearty dose of cloudy lake water from the swampy areas.

Caitie: Great in my daughters axolotl tank. I have never had issues. Easy to clean too.

Adam: I love sponge filters, and wanted one for an empty spot in my sump. This one if large and just the right size for it, otherwise I would have needed two of the smaller sizes. It may be to large for inside the tank, but great for my needs.

EDDIE K PHILLIPSEDDIE K PHILLIPS: Editing for understanding sponge use. (FYI, I use my husbands account.) I'm using a whisper 300 air pump on this 150g aquarium (I left the translucent pipe on for this one). The better the air pump the better the sponge's work! On a nano Petco 3.5g tank I over filter with a 4" sponge, but I use the air pump it came with. On my Hugger 3D 8-6g nanos I use about a 3" to 6" tall sponge with a 150 whisper air pump. On 20g tank I use 5.5" tall 4"w sponge but it works best with a whisper 300, but a 150 will do, just shorten the distance between the pump and the tank it's pushing air into. The faster the bubbles the better it cleans. Fish adapt to the flow. The flow can be altered by making the translucent pipe longer shorter or TAKING IT OFF! You can also purchase a air split valve. Pending your preference. Be mindful... restricting the air will limit the sponge's effectiveness. I hope this helps someone. I wish I knew before trail and error. ;)

Over 20 years into this hobby and I am changing my artificially planted 200 gallon aquarium into a planted aquarium. (Seen here: I purchased a few live plants from Amazon, the tree stump with a hole in the top is also from Amazon. See...
