hi, I was wondering about the importance of oxygenating the sand bed.
I have a 20 gallon tank with about 3 inches of sand. The sand was mostly just non-living aragonate but I seeded it with some heavily populated sand. Somehow the dark, dirty live sand made it down below most of my new sand. There's still a large copepod concentration everywhere. I can always see at least 50 of them running around, but I worry about the ones that have died below the sand, because the line (that used to be brown because the of the darker color of the live sand) is turning grey-ish, as if it is decaying.
I was thinking of something like a diamond goby to turn over the sand and mix it, but I don't want to completley decimate my copepod population, becasue then other things might starve. Being a 20 gallon tank, the diamond goby is porbably too big. So I was wondering what else could do the job well and fit in this tank. I already have a huge fire shrimp, a peppermint shrimp, 5 hermits, 3 snails, and one small green chromis, and a couple small SPS corals.
