Hello all, I am very new to reef tanks, just 6 mths. I currently have a 125 gallon African Cichlid tank which I had for 2 years but have been doing fish for about 12 years. My husband and I decided I needed a hobby and the reef tank has proven to be the one. I have a 72 gallon bow front with 100 pds of live rock, about 2 inches of live sand, 1 hairy mushroom, 1 leather toadstool, 1 kenya tree, 1 frogspawn, some zoas, some button polyps, 1 yellow eyed tang, 1 sixline wrasse, 1 pygmy angel, 1 flame hawk, 1 watchman goby with a mate, 2 conchs, 1 peppermint shrimp, blue legged and red legged hermit crabs and a few snails and a bunch of baby snails. I have a sump with a marineland 100 skimmer, a wavemaker and two koralla evolution powerheads (is that what they are called) and metal halid lights with moon beams and the actinic lights. This hobby takes a whole lot of time and I still am scratching my head wondering why why did I do this. But I love it and I would love LOTS of advise about ANYTHING
