Here is what I did. I have the light off for 3 months when I first start my 210 gal with 120 lbs of dry rock in to do the cycling. I start growing the chaeto in my refugium/sump with 5 hours of light 7days a week since day one. When I switch on my main lighting at the end of 3 months. I setup the lighting in my display tank with 5 hours a day and increase 20 minutes every week. I may be lucky, I never come across any ugly stage. And now my tank is about 7 months old, and all my SPS and LPS are growing fine with good color as well.
