2.5”x6” scrubby and felt adhesive pads for Float-500. Use on glass only.
If you have this, do you have to use two hands to clean the glass? Huge!
PS the back says “ it floats and it’s fun !”
Found a second pack. Tell someone who has a huge tank and a Mag-Float 500 Extra Large. Soon I may try cutting them into smaller sizes but it seems a waste.
