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

I want to write this review because this produce is doing a fantastic job in my reed aquarium. I have this installed on my intake for my hang on the back protein skimmer while I am fighting a lot of algae. No algae makes it past these guys - these are like algae blocking juggernauts. Get them out of the package, rinse them off well, they're durable and easy to use. I have nothing buy satisfaction with this product. When they clog, remove it and reinstall one that was in use previously that you rinsed the algae out of and cleaned thoroughly and you're good to go for as long as it takes to clog it again. If you buy one, I hope you're as satisfied as I am.

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!

Yes, they come vacuum sealed and flatter than pancakes! A few minutes in water, they start to fluff back out, and once it's on the uptake tube, it LOOKS round. **FITS the Fluval 07 series strainer & uptake** to just above the strainer. (I place a no-metal hairband on the top to keep the shrimp safe from going *inside* the sponge from the top and getting sucked into the filter. I think they are well made, and the inside bore leaves OVER 1/2" of sponge at the bottom which is GREAT for filtration quality. These were EXACTLY what I needed. Glad I didn't let the negative reviews stop me from trying these! (And, I did not note any odor to these at all.)

bought these to cover over the intake tube on the fish tank filter to keep out small fish or frye that would either get sucked up into the filter. It also acts as a first stage filter. I use a zip tie to keep them on... Works great

I needed these so bad but, had a hard time finding them with a 1" dia. hole for fitting on intake tubes. These fit great! They are a little finer than my previous ones but, that has not impeded water flow and they feel like they will last longer. Came vacuumed packed but, plumped up nicely running hottish water over them. then squeezed them out in tank water. Just started using them so we'll see how long before they clog but, seeing as how I clean them once a week that should not be a problem and may keep the canister filter cleaner.

Ordered the 0.6 inch size. I have the Top Fin PF10 Powerstream filter that came with the Top Fin 10 gallon tank kit. The inner diameter is snug for my filter, but not too difficult to put on the intake tube. I think snug is probably good if you have smaller aquarium pets like shrimp. Didn’t have to trim the length either. Puffed up nicely in water as their instructions say.

Keeps the fish in the tank. I have a top fin ten gallon tank, I’m using these to help keep fry and debris out of my hang on back filter as well as a few shrimp I have in the tank. It helps filter the water as well. These sponges seem to work well so far. It’s only been a couple of weeks and I’ve only used one so far. The pack comes with six and they work so well I don’t think I’ll ever use all of them. These will probably last me forever.

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.

very fast delivery. no issues at all

Très satisfaite

Not acceptable for Aquaclear HOB's. Too fine, too small, too short. Not at all like what's pictured, don't waste your time or money.

Fits well but clongs very quickly..

Got them today. Nothing like pictured came crushed by the vac slealed bag and has a hole punched all the way through with the core pushed back inside
