I'm looking into possible getting some corals but still learning every day. I have a 12 gallon fluval edge with upgraded lighting, Fluval edge savior David 18 watt LED, I'm wondering what I can do with this. I'm wondering what are some easy starter corals that don't take to much work and care. I also am using tap water as well and treating that. I stay on top of my tank and do 1 gallon PWC mon, wed, and fri. Let me know if you can help me out and put some beauty in my tank.
