I will try to answer more questions this weekend and will post pictures too. We are going to start the tear down process and look to see what is under all of that existing sand and live rock.
We plan to do some hard corals up high (i.e., not too deep), maybe some live plants, soft corals and low light corals down on the lower levels. We have some experienced folks in our group which is helpful. Thanks a ton for your insight. I may try the 4 x 400w and see where it gets us. I think we already have 2 x 1000w lights that we can use too. Man, I thought the 400's would do it. Some days I think I get it.
BTW, I am not new to this hobby, but I am new to this forum. I like it. I am Mr James over on RC too. It's almost midnight and I am sure th wifey is peeved I am still on line. Will post more later. Thanks again for all the insight and keep teh suggestions coming. I appreciate it.
