Yea, i was just wondering if this was the same thing as what is in a wet/dry or similar and if it would be a good/bad idea to use.
They are called BioMate filter media balls, and the ones I'm looking at are Foam-filled (the help with biological and mechanical filtration). Was just wondering if they would be a bad idea. (They kind of seem like what is in a wet/dry, and I've been told that bio balls create a problem l8r on down the road. I don't think these are "bio-balls" but not sure, they are foam in the middle.)
