Ahh , I thought thats what you meant. lol Well... I was trying to leave as many cave and crevices for all the fish and inverts. With leaving as much of the sb available for nutrient export. Coral space was important tho, and I felt it was a good compromise with the pieces I had. I also was thinking of our 2 year old and how the tank looked from his vantage point. This is just as much for him as it is for the two of us adults. so there was a lot of kneeling looking up at the structure as I was building. It made for a couple of awkward moments.. my father was here helping me and he was asking if I was alright"you ok? you need to take a break?".. No dad, I was seeing what it would smell like if I was a midget.lol
