ive had 12 bioballs in my canister for months now and they seem to be
pointless.

What are you trying to accomplish? Bio filtration or mechanical filtration
or both? How do you know they're pointless?

can anyone recomend something they may work better.

In what way? Is your water cloudy? Smelly?

the
canister uses a sponge and theres plenty of free space.

Try adding another sponge and a bag of those smaller bi-beads.

thanks for any tips
