I shoulda asked this question 3 weeks ago before I set up the tank but i just found this board today. My goal is a reef tank with mostly polyps and shrooms with a few lps and leathers. I hope I have enough light and circulation. Hopefully u can help me out. 10 gal All Glass w/glass canopy. 20" Current 40w 1 lamp smartpaq 24 hour lighting w/lunar. Cascade 100 power filter on back. Current Fission nano skimmer set on high inside. No uv sterilizer. 10lbs Tonga lr and 10 lbs ls. I wanted to go with a millenium 3000 filled with live rock frags but the guy at pet store said id have too much flow for a 10 gal. So, what do u think? Do I need more lights? How about adding a power head? Is a mill.3000 too much filter?
