I broke up sheets of that eggcrate light defuser stuff into small pieces. Was a pain in the butt to break all up, but its cheap, and has been working perfectly for 3 months now.
They work best when they have access to O2, you'd be better off using ceramic rings, lava rock, biochem stars or equivalentrdeandavidson said:can i use them in my canister (xp3)?

*ahem*
question- arent bioballs also designed to help oxygenate the water also as an additon to bio filteration?
isnt oxygenation lost (reduced) when you use pot scrubbers?

but if you insist on using them.... I would say the dollar stores would be cheapest
Oddball said:I have no idea how a static piece of plastic is supposed to oxygenate the water. Bacteria forms on the surface of bio-material and USES oxygen. The main gas-exchange that oxygenates the water is the air/water mix in the gravity drain pipe (mostly used up in the bio-chamber) and the surface agitation of the pump return to the tank surface.
