Well I have 35lbs of brand new C.Rings. And about 30-40 glns of bio balls.
I'm trying to see where I should put more effort into... Rings or Bio Balls?
Scrubbies catch my eye like crazy but it's to much of a pain to take out the B.Balls to add scrubbies (maybe in the future but this DIY 100gl sump has drained me Lol
I have sponges making up 90% of my sump media. The other 10% is a handful of bio balls that I will soon be removing and replacing with more sponge. For my set up at least, bio specific media is a waste of the space.
100% ceramic. ill never use bio balls or scrubbies again. ceramic media can be completely submerged, and that means no messy baffles, dividers, or drip trays.
