I started my first SW tank two weeks ago and have a question about the cycle. My tank is 56g with almost 60lbs of live rock (taken from tanks that have been established for over a year), 20 lbs of live sand, and some regular aragonite sand. Along with the rock came a brittle starfish, a bunch of snails, some copepods, Bristleworms, etc. I've been monitoring the levels for a while which were reading 0,0,0 for Ammonia, Nitrite, Nitrate for a while. I decided to use the shrimp idea to jump start the cycle. A few days later I was reading 0,.25, 40. Now it seems I'm reading 0,0,40+. My question is, am I ready to do some water changes to bring the Nitrates down? I'm guessing because of the active bacteria in the rock and sand (mainly rock), my tank only did a mini cycle? I may have seen a slight green tinge in my Ammonia at one point, but nothing major. I have since pulled the shrimp out btw.
Thanks!
