I forgot to mention something I do....Take lots of pics. Many time I do find the perfect Hardscape as I'm going ...keep trying other looks....then can't remember the one I liked and should have stayed with
Also, If you need to disassemble, tae pics along the way.
I'm setting my hardscape in my Riparium now(new build). Once I figure it out I'll pull the Mopane out to add MTS & sand Cap, filter & heater, then re-assemble. Pics help with keeping it consistent with the vision.
Best of luck with you new aquascape
