AQUANEAT 6-Pack Pre-Filter Sponge for Aquarium Shrimp Fry Fish Tank Filter 0.8” Intake, Replacement Foam Cover

These little sponges ended up being exactly what I needed. I was just trying to keep baby guppies and shrimp from getting sucked into my canister filter, and this did the trick without messing with the flow too much.It slid right over the intake — no trimming or forcing it on — and it fits snug enough to stay put without zip ties or anything. The sponge itself is a good balance: fine enough to keep the small stuff out, but not so dense that it slows down water flow or clogs every few days. I’ve already seen my shrimp hanging around on it picking off bits, and the fry seem to like the calmer flow near it too.Cleaning it is pretty easy — I just give it a squeeze in tank water during water changes and it’s good as new. Still looks solid after a few rinses.What I liked:- Perfect fit, no cutting or fiddling- Actually works for small shrimp and fry- Doesn’t mess with the filter flow- Rinses out easily and holds up wellNothing fancy, but it solves the problem without hassle. If you're running any kind of tank with tiny swimmers, this is a simple add-on that just works.

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!

I got this product for my killifish tank because I have some shrimp that are breeding and the babies end up in the filter, and this helps combat this! It also helps my tank stay clean, along with helping getting any plant matter to not go inside of the filter. The sponge material is pretty thick and coarse, but it's still really easy to get onto a filter pipe. They come squished in a vacuum sealed bag, which is r4eally good for storing the rest, but you need to let them soak in water so they expand before you try and put them on, they also go on very snuggly on my filter, and take just a tiny bit of force to secure onto the pipe. They are built great, just any normal sponge filter material, I recommend this product if you have any fry or baby shrimp like me that kept getting sucked into the filter!

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

It’s great to use over my filter intake because without it my Cory’s kept swimming into the filter and dying. Durable. Easy to clean in old tank water. Thick enough and very durable. Comes with lots of them too. Great value for your money and works very well!

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

The pictures you see are not what you'll get and are not tight enough with having to cable tie them in place. These come in a thoroughly flattened envelope within an envelope within another envelope. They are incredibly flat and in a pouch shape not round or cylindrical as shown in the pictures. The instructions say to let them soak for 5-10 minutes. Did that and they puff up a little larger but still are somewhat pouch shaped, not really cylindrical. The foam included is also not as coarse of material as shown in the pictures. They are much more dense foam and will require more suction power to draw water through them. These will decrease flow ability of your filter because of the smaller hole sizes of this sponge material. I also have problems getting them to stay on the intake tube adapter and had to cable tie them. I might as well have wrapped a dish cleaning foam square around the tube. The ones they specify for Aquaclear 20 are the right length but way to big of a hole and fit very loosely.Not real thrilled with either the flattened shape (they are clearly manufactured as pouches in shape), or the grain of the foam. I'll be lucky to not have to remove these for cleaning daily due to the small openings of this foam clogging. This is more like final stage foam filtering than the very coarse grain wanted. Just not the same size as pictured at all. I expected some reduction in flow.But while not closely measured, I would estimate water intake to now be less than 1/2 of what it is was without them. I wanted good flow but the ability to protect shrimp and snails too. They do that but at a reduced flow.I left 3 stars as they might work for a day or two in an emergency but are not well suited for Aquaclear filter intakes due to the finer grain and very loose fit. A smaller HOB might be somewhat useable as they don't pump as hard, but expect 1/3 to 1/2 the water movement and your water will likely warm up too.
