ALEGI Aquarium Sponge Filter Pad, Bio Filter Media Foam Sponges, Cut-to-Size Foam for Fish Tank (20"x20"x1" (35PPI))

Glad I bought this 1.5" thick sponge filter. The price is good and using proper expansion steps the sponge expanded to the exact dimensions. At first I got it out of the package, it looked like it is sticking to itself and is way smaller than in the description. I soaked it and then placed in the dryer on low heat for 30 min. Worked like charm. Highly recommend it.

The ALEGI Aquarium Sponge Filter Pad is perfect for my tank setup. It’s easy to cut to size, provides great filtration, and holds beneficial bacteria really well. Water stays clear, and my fish are happy. Excellent value and quality—highly recommend for any aquarium!

Works great, cutting to size for my pond and fountain pumps. Much more economical than buying pre-cut from the pump manufacturer.

Comes scrunched up, needs to be wet then dried to stretch out & expand for 24 hrs other than that it’s great sponge pad for aquarium

Takes multiple days laying flat to expand to advertised thickness. I have no problems with it, works great.

It's foam! And it functions as a filter! So does a sock. But this is better! Lol. No, good quality - I have to wash the crap out of them (literally and figuratively) every day, sometimes twice, and they are holding up awesome, with a whole sheet ton of more... See what I did there? They catch the stuff. I've noticed a difference in my tank, honestly. I don't understand who would make this, repackage it, vacuum pack, ship, and warranty for... Pennies?! Great quality. Top notch.

Just what I wanted. Packaged nicely arrived on time. Working great.

VERY dense but maybe I got the wrong count. In Pond filter. Definitely catches gunk...but ducks shredded it.

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.

Good product and exactly what I ordered

Excelente producto y precio

This thing is about 18" by 18 " which a can live with, but its about 1/2 inch thick. ITS NO-WHERE NEAR 1.57 INCHES THICK. For $30, guys, seriously, talk about skimping on quality. You'd think you were cutting cocaine!!!

Great for my rain barrel that goes into my pond to clean the water
