the rock work looks nice i myself is a fan od a lot of rock. one thing you might want to think about is holes for frag plugs. I have a lot of rock but the only thing is that i sometimes need to take the rock out to drill holes for frags or need to glue them to the rock itself. something you might want to think about if your planning on doing SPS. it seems like you have a couple of good spots. i also ike the caves that you have small but good enough for fish to hide in. On the flow how much are you looking to spend on pumps.I think since most of the rock work is settle to the back wall two good sized pumps will do good with maybe one small one facing the rear to keep detritus for settling in the back of the rock work. said:
I am wanting to do a mixed reef but still not sure if I want to take the plunge into trying to keep SPS. In saying that; I would still like to be prepared for it in case I jump off the cliff in the future. I have anywhere from 2 - 6" of clearance from the rocks to the back glass panel and I am a little concerened about dead spots behind the rocks. Would I need to place a small powerhead behind the rocks to get some flow behind there as well? To answer your question on price range, I am looking at spending 150 - 225$ on powerheads to start out with and then go from there.
At Nextwave I believe that Dr. Ron had mentioned something about using milk to to be able to visibly see how the water is flowing through the tank. Has anyone used this method before or is there another product that could be used to help locate dead spots? Thanks again for all the help.
