setting up my first tank its a 75 rimless tower. So to explain before I add the pictures I took some 1 inch pvc and measure the inside of my tank and made sure cornerflo wasn't an issue, then begin building a scape inside the pipe area for at least an inch of clearance from glass for final product. Have 3 nice arches. But as far as a newb scape with a 30 inch tall tank. How did I do? The peak in the back makes it almost to 2/3 line of my water volume. I want to do an sps dominant tank so wanted to make sure plenty of area higher in tank for it to grow. Pictures is front, right side, back(cornerflo area), left side. Has no glue, epoxy, etc. Just sitting like this mostly stable. Please share ideas comments.
