Aquatic Experts Aquarium Polishing Filter Pad, Water Polishing Pad for Aquarium Filters, Filter Floss for Fish Tank Filters, (50 Micron, 24" x 36" - 1 Pack)

The big difference between this and other brands is that Aquatic Experts treats one side of the filter pad to reduce the chance of strands of the filter media coming loose. For other brands, you will annoyingly see strands of the filter media in your fish tank from time to time. Because the texture of the treated/untreated side is different, its easy to place the filter pad in the correct "direction". This means that this filter pad will last longer and can be reused a few times. I cut extra pads for my filter. When its time to change, I put in the newly cut pads into the canister and rinse the dirty pads and then soak them in a bleach solution which releases the dirt. With sufficient pre-filtering with fine filter wool, the pad has no problems lasting for 1 month+ (not sure why some reviews say theirs lasted only 2 weeks - not enough pre-filtering?)

I really doubt this is for aquariums as one side of the pad has some type of coating which seems more typical on materials used for clothing and limits water flow between the material. It looks like someone bought to much of a clothing liner material and is now trying to flog it off as suitable for aquariums. It didn't really work as suggested so will stick with known manufacturers of aquarium products. I don't recommend this product.

This Aquarium Polishing Filter Pad works perfectly. It is bit pricey.

Works great. Will buy again

Really helped clear the aquarium water. Added on top of the foam sponge and unbelievable how much it picks up. Sure you have to cut the size you need, but really no big deal because price wise, this can't be beat.
