I have started a new saltwater tank about 2 weeks ago. It's a 90 gal tank with sump. I'm using live rock to get the nitrate cycle started, ph is 22. I'll be adding coral later. How long should I wait to add fish? To add coral? And what are the best fish and coral to start with? I have a 75 gal freshwater with african chiclids and wanted to try my luck with marine life. Tnx for the help.
