Hagen 24 -Pack AquaClear Quick Aquarium Water Filter Refill Cartridge for Power Head Attachment

Exactly as advertised. Will order from again.

These work so good as an added filter

Great value. Keeps my tank crystal clear. Easy to change. I use two on my 210 gal. Tank in addition to my regular filter. Very happy with it.

Fast delivery packaged well, easy to open. The exact product from description

excellent.

Better price than buying individually. I have a turtle so I through a lot of them.

Used these along with their power heads for years on a 150 gallon reef tank. They are also a MUST even on a Nano tank like mine. Ends lots of problems!!!!

These filters work excellent for polishing your water and will withstand being cleaned multiple times.

These are great fir keeping water clean. I replace once a month; takes about 5 minutes per AquaClear filter

good
