How do you all feel about the plastic bio-balls? You like them? Dislike them?
Disclaimer, I added some underneath where the filter sock would go and it helped quiet that section down a lot. My initial thought was to try and get the fluidized media action like K1 media chambers. But it doesn't get enough movement to create that.

Also, how do folks here feel about pot scrubbers (e.g. scrub buddies from the dollar store) for added biological filtration surface area? Same concept except different material and much less expensive. I personally have used those to help seed new tanks. I added a couple scrubbers from my fluval into this sump for example.
I understand adding bio-balls or pot scrubbers can become an issue for some with a heavy bioload where it can become a detritus trap. Or as some call them, a nitrate factory. So I am curious to hear what you all think about these.
Is too much bacterial filtration a bad thing?!
