Here are the issues you need to correct for your tank:
-Your alk and nitrates are much too high (alk = 143-214, nitrates < 20-30)
-You need some powerheads (MaxiJet or AquaClear)
-You definitely need a skimmer (Excalibur, Coralife, AquaC)
-Your tank is tremendously overstocked
-You should definitely remove the air line and just use powerheads
I did not read the entire post, but I am sure Sepulation has helped you quite well. :happyfish
