Hello, I am starting a reef tank after a ten year lapse. Everything is so different, I have a 21 gallon tank with a 10 gallon sump. I just added my bacteria yesterday, today nitrates are 15 ppm. I have mostly dry rock, but I bought a chunk of live rock from LRS. Even though I have a freshwater tank I am nervous about the cycle with salt water. I have copepods and chaeto coming next week.
