Features

  • Dimension: 8x4.5cm/3.2 x1.8, the inside hole diameter is 2cm/0.8; for a snug fit, check the size you need carefully before placing an order.
  • Lifesaver: Keeps baby fish, shrimp, and snails from getting sucked into hob filters, power heads or canister filters by simply putting a pc of this pre-filter sponge over the intake.
  • Improve Filtration: Does a good job in catching flake fish foods, plants and any other large particles floating in the water keeping the tank cleaner and last longer between cleanings.
  • Maintenance: Rinse the sponge roll periodically based on the bio load of your aquarium tank. The material holds up well to being rinsed and reused and allows great water flow.
  • Includes: 6 pcs of pre-filter sponge (Note: The hole doesn't go all the way through the sponge. They come flattened in a vacuum bag; just unpack and rinse them and these sponge filters will puff up to normal shape and size.)

  • Work Great Soak First
Size: 1.8"D X 3.2"H, 0.8"
I recently purchased the AQUANEAT 6-Pack Pre-Filter Sponge for my aquarium, and I couldn't be happier with the results! These sponges are a game-changer for anyone looking to keep their tank clean and their aquatic pets safe. The sponges fit perfectly over the intake of my filter, preventing baby fish, shrimp, and snails from getting sucked in. They also do an excellent job of catching debris and large particles, which helps keep the water cleaner for longer periods. One of the best features is how easy they are to maintain. Just rinse them periodically based on your tank's bio load, and they hold up well to repeated use. Plus, they come in a vacuum-sealed bag, so they puff up to their normal size once you unpack and rinse them. Overall, the AQUANEAT Pre-Filter Sponges are a fantastic addition to any aquarium setup. They provide both mechanical and biological filtration, ensuring a healthier environment for your aquatic pets. Highly recommended! ... show more

  • Works great
Size: 1.8"D X 3.2"H, 0.8"
These work amazing I have an axolotl tank and a beta tank and both like very low flow water and on my axolotl‘s tank, I was able to put one of these on the outflow bar for my canister filter and one on the outflow tube for our chiller. They fit perfectly and immediately cut down the movement to the water. Now the only movement I have on my tank is the bubbler my betta tank has a small internal filter and these were a little bit big fitting on it. I was able to kind of maneuver it towards sitting on there now if it falls off, I most likely will have to put a zip tie or something on it but either way it’s also helping in that tank these are must have just taken them out of the package. I put mine in water for about 30/42 opened up the middle a little bit of water getting in there and then was able to fit it right onto my tubes ... show more

  • Perfect pre-filter for Aqueon aquariums
Size: 1.6"D X 2.8"H, 0.6"
My Aqueon Minibow 2.5 aquarium holds Emerald crabs, Hermit crabs, and some Nassartus snails. They live in saltwater. These filters help to collect food debris and algae that cloud the tank. They cover the inlet on the filter unit. This reduces the buildup on the impeller, but debris will continue to reach the Aqueon filter pad. When the filter was near the substrate, two things happened. An Emerald crab ate the debris or climbed the filter. It also hid under it. (It probably was molting or hates the bright aquarium light.) These pre-filters are affordable and easy-to-use. Try a pack today. ... show more

  • Functions well
Size: 1.4"D X 2.4"H, 0.4"
I'm still using my first one out of the box. They fit well on my filter and help keep fish from getting stuck. They are sturdy and work well at assisting with filtration. They are easy to rinse out and replace

  • So easy to use and they work well!
Size: 1.8"D X 3.2"H, 0.8"
These are a must-have for any aquarium owner with a cascading waterfall filter. These sponges are the perfect size, easy to install, and do an amazing job of keeping my aquarium clean while protecting small snails and shrimp. I highly recommend these for protecting small creatures that live in your aquarium and for ease of use! ... show more

  • Works Great
Size: 1.8"D X 3.2"H, 0.8"
I read quite a few reviews and many complaints that the shape was wrong. Yea out of the bag they are very flat and square. If you follow the instructions and soak them for 10 minutes they puff up as expected. You can see in the the photo that one on the bottom is after soak and the other two are directly out of the bag. ... show more

  • Start Flat, but Puff to PERFECT!!! Love them. Thanks.
Size: 2.2"D X 3.9"H, 1"
They look weird when you get them, all flat and I mean FLAT and thin when you get them. Don't be fooled. They puff up on their own. I set mind on a rack and came back the next day and they were all puffed out and looked like the picture. They are super great for my needs--stopping a fancy water moss from its strands going up the strainer and stopping the newborn baby fish from likewise going into the filter. Great product. Thanks. ... show more
