Two Little Fishies ATLPBRFD 2-Pack Phosban ReaCountor Foam Disks

OEM replacements for the original reactor disks. They are the right size and they filter, what more can be said?

I keep one or two extra of these on hand for when I change out my GFO not worth rinsing the old ones out when they are so cheap. If you are using pellets you don't need these.. you need to get the mesh one.
