So I'm new to this hobby, and im loving it, but there is still a lot I don't understand. I have a 10 gallon reef tank, it's 1.5 months old. I added bacteria and fed fish food to begin the cycle. I did a large water change ~the 12th in when nitrites were on the decline, and added 2 small clownfish and stocked some corals. I knew I rushed things too quickly, so I monitored my levels. About 4 days ago, ammonia was <.25ppm, nitrite was maybe ~8ppm, and nitrate was ~120ppm. I did about a 30% water change. I was thinking about buying chaeto to help with nutrient export, but I checked my levels and everything was 0! I thought that nitrates slowly built up, and we're exported through water changes for the most part. I have mainly soft corals, which I read Xenia can take up some nitrates. Is this normal?
