Koi Pond Filter Media Pad - Cut to Fit Roll (Dye-Free/Blue Bonded) - 1.25 Inch Thickness (6 ft, Blue)

It works well

Added this as an additional layer to my pond filter. It really absorbs the crud and then cleans up easily. So far one section has lasted through five cleanings. Has made a big difference in keeping my water clear.

Seems to hold together much better than batting purchased at Walmart

Used this to get the murky water clear in my pond. It took about a week and I needed to clean the product multiple times because it trapped all of the small particles.

Unlike others, this product measures well within what’s stated. Additionally, it’s very durable and holds up to a few rinses. I use this in a 40g sump, filtering (2300 GPH) a 210g African Cichlid tank.

Much more value for the money than other filter material that I've used.

I used to have a different sponge filter that did not catch the fine particles nor did it polish the water, every time I pulled my old sponge filter you would see all the brown water fall back into the pond as I lifted it, it was so annoying.This sponge filter catches most debris, polishes the water and when you pull it out it will not release all the dirt back into the pond, dirt stays trapped in the sponge, you rinse it and it will perform over and over.So I have to give it a good rating.

Better clean water
