ALEGI Aquarium Sponge Filter Pad, Bio Filter Media Foam Sponges

I originally purchased the ALEGI Aquarium Sponge Filter Pad for a very unconventional reason - and I’m so glad I did. I tried to reorder replacement filters for my pet water fountain only to find out the fountain had been discontinued and the brand no longer carried the filters (so frustrating). Customer service suggested I try an aquarium sponge filter pad and cut it to size, saying it would work just as well and be far more affordable. They were absolutely right!! This sponge pad is fantastic quality - dense, durable, and super easy to cut to fit any filter compartment. I was able to customize it perfectly for my pet fountain, and the water is flowing clean and clear just like it did with the original filters. Bonus: I realized I can use this one pad for multiple filter replacements, which is a HUGE COST SAVINGS compared to buying brand-specific cartridges over and over. Very happy with this purchase

These work perfect for cut to fit filters I made my own filter after 4 years a failed filter designs, The one I made is half barrel bottom 18 inch these filter pads can be trimmed perfectly to that size. With these filter pads I only have to change my pads once or twice a week in the summer, and once a week in the winter. Love them. They seem to be holding up quite well.

Perfect for my 10gallon tank . Easy to cut down to what I needed. I put rocks in that got it all first so had to pull it out to clean it off and it washed out with no problems. Very happy with this product. I used this for my paludarium for the bottom of the tank on the land side.

Nice Filtration Perfect quality Good price

I have an automatic cat water bowl. It calls for 2 kinds of filter. One is a fancy charcoal one that sits on the top and keeps the water tasting (I assume) nicer. The other is a foam one in the pump itself to keep things like bits of cat food and hair from getting sucked up into the pump. I have several long-haired cats so the little foam filter was always getting clogged up faster than the fancy one so I'd wind up needing more of the foam before I needed the charcoal. So, I bought this and cut it down into little chunks the same size as the ones included with my water fountain. The foam is, to my eye anyway, identical. It does the job of keeping the filter hair-free and I got probably a year's worth (filled a 1.5 gallon ziploc bag) for a fraction of the price of buying the 'two kinds of filter' kit.

So apparently the filter I ordered just came without instructions. After reading other reviews i tried soaking the filter itself in warm water for a bit and it puffed up to full size. Now its useable and seems to be a decent filter. Definitely a good size for the price.

I use this in my estimated 285 gallon garden pond. So I only need about 3 in by 3 in squares to cover my submersible pump (24 watt 800 gph) intake valve. The pump will run non stop for about 3 days before I notice a performance drop in the aeration fountain thrusting up from the pond. I don't use an outlet extender for the output valve tubing. So instead it thrusts up from 16 inches of water and typically caps off about 6 inches above the surface. It's 800 gph strong and the point of this review I'm totality is that these are durable, a good value, and well made.

Sponge shipped in vacuum collapsed mode but restored to proper thickness with warm water.

I see a lot of negative reviews in regard to product not being the correct thickness. Maybe you didn't receive the card explaining what to do, I don't know. All I did was fill up the sink with hot water and soaked it for 30 secs, rung it out, put it in the dryer. It came out perfect as you can see in my video. No issues and it's exactly as described. Perfect for my aquarium filter.

I am using this sponge filter pad to help keep my garden fountain debris free. It is excellent for filtering out larger debris that gets deposited in the fountain by birds and the wind. I simply cut the size of sponge that I needed and wrapped it around my fountain pump, securing it with a large rubber band. I have layered it over another cloth liner that filters out smaller debris, like algae, and between the two layers my fountain is nice and clear. Once a month a take the filter sponge out, replace it with another than I have cut from the larger sponge, clean it and lay it in the sun to dry out thoroughly thereby ensuring that no organic matter is growing in it so I can reuse it in the future. I highly recommend this product.

Very functional very durable, cut to fit. Very easy to clean. You can get multiple uses out of this product. Good value
