Well, it was a 30gallon frag tank, but I never could get it to balance out and jive. The nutrients would crash, and then skyrocket repeatedly. Which lead to dino outbreaks, followed by algae. My first tank, 15 years ago, seemed to find its groove, and steady out. As far as pests, I ended up with them anyways in the dry rock tank, so I’m not super concerned with that. The only seeding I did was a bottle of bacteria, and I don’t remember which one it was.
Another question I forgot to add, does 50lbs of rock per structure sound like a decent starting place?
