Aside from ones I have sold or ditched, this is what I have running:
92 Corner ~6K
29 Nano ~1,500
24 Nano ~1K
54 Corner ~1,500K
100G Frag ~1K
Corals and crappy equipment another 5K. I have really found some deals though like: free chiller, swapped frags for 2 X 175W MHs, free 54 corner hood, free pumps ect... and buy used now.
Oh, electric? Who knows (~100+/month)?I have 4 separate MH setups, VHOs and PCs.
