Superfish Hang On Cartridge (2 pcs)

The dual-action design really cleared up the yellow tint in my tank within a few days. I like that it has both the carbon foam and the two micro filter mats for thorough cleaning. My fish are much more active now in the cleaner water.

The carbon filter foam and two micro filter mats fit perfectly into my hang-on filter and cleared up the slight cloudiness within two days. Keeps my water looking clean with noticeably less effort than my previous pads.

My tank cleared up in under 24 hours after installing these, and the dual micro mats caught all the floating debris the old filter missed. Exactly what my betta needed.
