Need help, advice, kick in the.........

[Glennrf38]

OK so let me start with some background. I have a 55 gal semicube, 20 gal sump, lots of live rock (see pictures in tank build section). Lighting is provided by a nice coralife 150 HQI lighting fixture. Bare bottom. Whenever I check the levels (which probably isn't often enough) they all seem to be good. Top up aprox. 5 gal every 3 days. Water changes every week or so. Skimmmer is putting out good skim. Running phosban and charcoal.

Now to the problem. Noting seems to be growing. 6 months of growth for my frags has got them almost over the edge of the frag button/holder thing. Everything seems to be doing well other than growth. All the fish are eating well. The tube anenome is eating well. The LTA is eating well whenever I can find him. I can't even get the cheato to grow in the sump. About the only thing that seems to be growing well is the green algae on the glass, which I try to clean off everyday. Any advice? Or a volunteer to come over and tell me what the h e double hockey sticks I'm doing wrong?

Let me know if you need any more info.

Thanks
