what are the cons and pros of Bio balls?

PROS
Bioballs and biomedia in general provide large amounts of surface area where water and air are constantly being circulated around them. This is a perfect breeding ground for nitrfying bacteria, the bacteria that convert ammonia to nitrite and nitrite to nitrate.
CONS
They do require a regularly scheduled maintenance program to keep detritus from accumulating on them.

I don't use bioballs but beads (smaller) I keep them in a mesh bag and just swish them around in saltwater I remove at water changes to loosen any solid stuff built up on them. That preserves the bacteria and keeps them clean.

"I don't use bioballs but beads" at a quick glance I was officially laughing my ass off (though there were 2 "T"s there for a sec). I ditched my bioballs along time ago in favor of rubble rock.

You bet! Especially for tanks that don't have large amounts of LR. I've see several posts that you need to regularly scrub each bio-ball. Don't do this. the slimy coating is home to nitrfying bacteria. just give them a whoosh in tankwater to remove loose crud. Water from a water change is fine.
A downside (if you consider it that)--they will do nothing to remove nitrate, just the more dangerous ammonia and nitrite. But, LR or an expensive reactor are really the only filtration methods that will remove the nitrate anyway. IMO: they are excellent filtration media for newer hobbyists or those with fish-only tanks who aren't ready to spend the $ for a sufficient amount of LR. Most of my filtration now is LR; but have kept many very healthy tanks for years with bio-balls being the main bio-filter media.

This is correct, but for most tanks we have plenty of nitrfying bacteria and for the few tanks that have high ammonia and nitrite over stocking and feeding is the main problem. So if this thread keeps going you can start to see why I say they don't do much of anything.

I use them when starting a new tank. After a year I toss them cause if you dont maintain them they can leach out nitrates after a while.
So IMO its easier for me not to use them then use them. After all, my tanks has a refugium with 1st layer live sand, 2nd layer crushed coral and 3rd rubble rock all on top of a plenum

Good idea...
