Setting up my first reef after 7 years of freshwater keeping. I do have a 1000 litre fresh water that I'm hoping to convert in the long run with another 200 litre to set up next. The first I'm setting up is a nano which has been up nearly 2 months with still high nitrate 80+. Fishless cycle bare bottom while ghost feeding. I'm doing two 50% water changes a week. I know bare bottom takes longer, how long can I expect? am I changing to much?
