Not starting anything but, you have a 29g tank, have you had larger tanks to back this statement up? I am curious, because any article, reef book, or forum you go on says that the more rock you have is better for the filtration. Yes, you can have less, but you better have one kick a... filter, skimmer etc. and excellent husbandry.
With the rock she has, and the open spaces....not jambed packed....she should be able to rearrange to create the open effect she is going for.
Good luck with this.
Azfishgal, I am sorry to vent here, but I felt it was necessary to defend what I was trying to say. I wish you all the luck. Maybe try to get some tonga branch, or other types of rock. It appears most of your rock is figi.....excellent rock, but not really artistic in shapes. I have a lot of it myself. I added some tonga branch to create openings for caves, very neat effect. Also got some buna branch that is awesome. Just a thought.
Don't be baffled. What I'm saying is that you do not need excessive amounts of live rock piled on top of each other to have good "bio filtration". In a mature reef, such as Azfishgals, there is such an abundance of bacteria that removing a few pieces of rock(if she wanted too) will not have a large enough adverse affect to be detrimental to the "bio filtration", or the tank as a whole. Remember, live rock isn't the only source of biological filtration within a properly designed reef tank.
Now, having a good amount of surface area of the live rock available for grazing fish is completely different, and you mentioned nothing of the sort in your inital post. This can be easily accomplished with careful placement and arrangement of the actual rocks that are chosen to be used. A big pile of rock(not saying azfish's tank is that, just saying for example), with not much of the actual rock seeing the light, is not any better then a carefully designed aquascape from a grazing perspective.

Since when is the size of the tank I currently own indicative of hobby experience and knowledge? FYI, I've owned many different size tanks(100 being the largest), all of which were very successful. I currently service not only my own reef, but 3 of my good friends reefs as well; which are: 45 gallons, 55 gallons, and 80 gallons respectively. All three are flourishing and were setup/designed by myself.
Good luck with your tank azfish, I can't wait to see it!
