Oh this will be fun. I don't know much about them as I got into the hobby after they started to phase out. I know there has to be a few guys here who have used bio balls and a trickle filter...or maybe still do

this is a huge can o worms... The theory behind a wet/dry filter with bio-balls was to promote the growth of aerobic bacteria that would help reduce the ammonia and nitrites, in realty it became a nitrates sink that became a issue feeding the algae. the other thought is that it helped to oxygenate the water but I think that breaking surface tension does more.

The 80's called. They want their filter back!
With the knowledge in this hobby and access to different ways of nutrient export. Wet/dry filters are obsolete in home aquariums. But however. They still have benefits in larger commercial systems.

They are only useful for tanks with a small amount of lr other than that use the space for macro it's far more efficient and super easy to get nowadays. Once turf scrubbers came out the bio balls faded away except for stores with massive livestock systems that have next to no lr.
I do use a couple handfuls in my sump where my overflow comes in but that's just to eliminate the noise of water running and micro bubbles rising lol.
