Features
- Dimension: 10x5.5cm/3.9 x2.2, the inside hole diameter is 2.5cm/1; for a snug fit, check the size you need carefully before placing an order. The sponge's inner diameter accommodates filter intake within 1.1-1.34 inches (28-34 mm) due to its elastic properties.
- 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.)

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.

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 well Nothing 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.

Fits a majority of my filter intakes from 10-70 gallon filters. They come vacuum sealed so you have to soak them before you install them. They are good at keeping large particles from getting into your filter media. You can also zip tie one to some tubing when doing large water changes if you don't want too much suction/if your afraid of sucking up small fish.

Bought these to cover my TopFin 30g HOB Powerfilter to help keep my neocaridina shrimp from being sucked up. It does lower the flow rate a little but otherwise filter still works fantastic, and my shrimp no longer can get accidentally sucked up! Fairly easy to clean off any trapped debris as well, just gently shake in the tank or rinse. My only complaint is the sizing is off. I bought the suggested size for my filter intake, even measured to be safe, and as you can see in my photo it was far too short and did not cover everything so I had to splice 2 together, so not the greatest fit and was a bit frustrating. Only reason I'm not giving 5 stars. I suggest sizing up a size or two from what you think you need. Other than that, no complaints!

Works for my canister filter intake, making sure my baby fish aren't sucked up inside the intake! Highly recommend. They last a long time too. I still have 3 of the 6 I bought.

I got these to to put over the intake of my Topfin Silenstream filter. It's the 5-10gallon one and it fits great. It's small enough that it doesn't slip off but still easy to put on. I didn't have any problems with it getting dunked up too fast and I went 2 weeks without rinsing it multiple times with no problem. I accidentally order 2packs so I cut some in half to baffle to outflow and they also worked great there. They seem durable and have lasted being squeezed many times.

Fits good, collects food and stuff saving the filter. Doesn't really slow the flow.
