I shutter at the "advice" you'll get there Matthew. At times you say some stuff that needs a counter voice, other times you say some stuff that blow me away. what you've picked up this far is amazing and I sure hope you continue. One thing I suggest is to take things slower then you are. If you loose something don't jump to instant conclusions and post them as a fact. This doesn't help you learn and only serves to get countered. What seems like an argument to you is hardly an argument.
Trust me, we're mild manor to what you'll get over on RC.
I think getting new lights will help. I also think a skimmer would really help you out. I have a CPR Bak Pak you can have if your RSM will hold it. I'll have to attach the brackets on it as I used it in sump (for 10 years). The pump is nearly new. perfect size skimmer for that tank volume, that is for sure!!!
