Hi. I would recommend even more base rock if you swing it.
You should have about 1.5 to 2 lbs of rock per gallon. And yep, the LR
will seed the base rock, I'm doing the same thing right now.
I inspect every piece of lr
i buy before adding it and I have not had anything at all get by me. I found a bristlworm once and a crab which never made it to my tank
I have 3 peppermints and one pistol and so far no issues, it's only been like a week or two.
hope that was helpful!
Post some pictures we'd love to see your setup progress
