Hey guys! I'm new to this site so there might be an answer somewhere else. any way! i have had tanks all my life but i have never set up a reef. i want to get one going now. i now have 40 gal tank w/ a aqua clear sump and protien skimmer. i am looking for some tips on saltinity, temp, lighting, and filtration. i currently have some palups, star palups, couple of xena, cactus coral, and a purple clam. my fish include, yellow tang, yellow eye tang, powder bule tang, and three eels. any suggestions would be helpfull. i want to make sure the tank stays healthy.
