So I have upgraded to a 40B and id like to get some ideas on aquascapes. I like the minimalist look but im afraid of not enough filtration and my sump is small so i cant pile rock in there. Keep in mind This will be an SPS/Zoa tank only with maybe a few acans. Im going to buy rock tmm but I have alot of shelf pieces to work with as of now. I definitely do not want the piled rocks against the back wall look. I was thinking either a half circle kind of look with my zoa garden in the middle on the bottom of tank or the bonnie scape which I love. Please add your opinions and any scapes that you like(with pics). Make sure the ideas will work in a 40B though. thanks guys
