lighting is 4 bulb t-5's ,rockstack and aqua scape ........yes was done by me. it's the 4th time i have rearranged and now i am finally happy. i am an artist and have the mentallity that it can always be better! but now i'm happy with my positive and negative space. i wanted to work it so it has a stadium seating for corals to lay out nice and i had more room to add pieces,so everyone would have space to grow. i will be adding (hopefully) a bunch of new pieces friday.thanks for looking and the nice comments
