My tank is almost 2 weeks old. My parameters are pH 8.1, Ammonia 0.03, nitrites 0, nitrates 0-5ppm(it's hard to discern the color). I started with live rock from my supply store as well as a couple prices of dry rock I bought and live sand. I have 2 clowns that appear happy and thriving. 1 zoa frag (I know I know, I've already been scolded enough for rushing, I get it) that arrived at 47 degrees that I'm fairy certain is dead. I'm definitely getting into the ugly stage and am planning on getting a couple Trochus snails and a couple Cerith snails to help clean up. I also ordered some copepods. I'm wondering if these snails would be good (I researched and I think they will) and also what the bubble looking stuff is on my rock? It looks like air bubbles trapped or something. I truly appreciate any help and advice! I do my research, but sometimes it's a bit overwhelming.
