Ok, I have a 150 gallon tank not set up. I got everything I need to start it up with except the lights. I’m starting out with coral. How long do I wait before I introduce my coral and how many is recommended to start with?...
Set up the tank. Get everything running. Measure the top 5 things in the water for 2 weeks. Get used to doing a water change. Figure out how to clean the sand and glass. Get a light. Once everything is settled, spend what you can afford on some corals and see how it goes. If they look good after a few weeks then get more.
