ALEGI Aquarium Filter Sponge Pad 30PPI / 40PPI / 60PPI Bio Sponge Filter Media Cut-to-Size Foam for Fish Tank, Pond Filter (39" x 4.72" x 0.78" - 60ppi)

⭐⭐⭐⭐⭐ Excellent Quality Foam – Perfect for Aquarium Filtration! I was extremely impressed with this filter foam. The material is thick, durable, and has the perfect pore size for biological and mechanical filtration. It cuts easily without falling apart, and once placed in the filter, it holds its shape perfectly. Water flows smoothly through it while still trapping debris very effectively. After using it in my aquarium system, I noticed clearer water within just a day. It’s also easy to rinse and reuse, which makes it a great long-term value. Highly recommend this product for anyone who needs reliable filter media for aquariums or sump setups!

Best thing i ever got. i didn't get the chance to use it for my tank but i did get to use it for my terrariums and it nice. its, durable, thick, function is nice and helpful for my needs in plants and terrariums. worth its money. only regret is that i didn't buy more then. i will buy again!

Work well with my tanks

originally thought product was far thinner than advertised. Apparently it needs to be soaked, because it is vacuum sealed for shipping.

I've Loved these Little adorable liners it works very well for making a homemade filter for my turtle tank it's easy to cut and clean to the size I needed

Perfect, exactly as described. Works great, easy to cut to size.

Was exactly what was needed will be ordering again as I have used up pretty much all of it on fish tank projects

I thought this would be half an inch. Is only 1/4" thinck. Will return for thicker size.
