I'm probably rushing things her and I know we have to have patience in this hobby. New tank has been cycling since 3/1/2021. 90 gallon with 40 gallon refugium. Dry rock and live sand. No livestock. Dosed Dr. Tim's on set up and ammonium chloride by the schedule Dr. Tim's recommends. As of yesterday, Amonia 0, Nitrites 1 and Nitrates 20-50. These parameters have been like this for at least 4 days now. Continue to wait, do a water change, or add Dr. Tim's one and only and see if that brings the Nitrites and Nitrates down some? We have 2 shrimp in QT and I feel so bad for them just sitting in there with no substrate.
