So I found someone, getting out of the biz, on CL, and bought 10 lbs of "dead rock"
for $3.00 a lb. I'm still not sure I agree with him, that I can just set up my tank with full salinity, and not worry about a mini-cycle (if he gives me a cup of salt water). I'm thinking I'll put my GSP in the larger tank, and keep the salinity the same (1.013) as my filtration is used to, and continue to slowly increase salinity. I still don't have a protein skimmer, and I'm told I don't "need" one, unless I wish to create a tank that is "maintaince free". So, I guess, I'll continue to plug along. I'll go ahead and keep both the fluval 305 and the emperor 400 on the tank. That should be more than enough water flow and filtration. This person will sell me a water circulation thingy that pumps 1000 gsp, when his tanks are all broken down. It seems that may be all I need to run a full marine set up, as a FOWLR. I'm still pretty confused :)
P.S. Oh, and I have plenty of crushed coral for my substrate, that I got for free!
