I recently overhauled my rockwork and migrated from the stale "rock wall" perspective to a column type design, to enhance my flow and improve the general health of the tank. I used 1/2 pvc to build the columns and drilled holes in my rock to build a more stabile base which will not topple if contacted during cleaning or other maintenance. (This has happened before and cost me a lot of time, stress and SPS growth). Here is a picture of the basic wall structure previously.
The new design has more opportunities for coral placement, better flow, more arches and hiding places for fish and is generally a lot more pleasing for me to watch. I'd appreciate hearing any comments viewers may care to leave.
Here are a few pictures of the new design:
Thanks for any feedback, suggestions, comments, etc. you have.
Fish wishes,
Mark
