All bio-balls created equal?

Thanks for the replies.

I was looking at Bio-Mate. They're more rounded than Lee's and come in 1" and 1 1/2" size. They are advertized as being "inert and non-leaching" and "will not clog up with organic matter".

Bio-Pak is offered in Drs Foster&Smiths' catalog but just looking at them makes me think they are more prone to collecting gunk. Thanks for the confirmation Jim!

Do people actually use the balls with sponges in them? To me (consider the source! :rolleyes: ) THAT does not sound like a good idea. I can't imagine ringing out each and every one of those little sponges!:eek:
 
Yup, blitzen definitely has topped me on that one. :p

beviking - I agree fully on the sponge-centered or sponge-totally bioballs. Why not just use a sponge? they can be perfectly good biofilters, they just do not self-clean at all. No, thank you, not for me.
