I would have used starboard in mine, if I could purchase it locally. Seems whenever I,m in Winnipeg I dont have time to get some and then its inconvenient when back home setting up a tank.
My rubble is easily siphon cleaned, although it does trap detritus. I just lifted my rock to an eggcrate platform, supported by 4in. pvc pipe. The pipe is horizontal though, creating homes for the fish. Not a look everyone would like but once grown over with corals, will be fine.
As the eggcrate extends more to the front than is covered by rock, I covered it with the rubble. Solved two problems, the look and collecting detritus. So my bottom is now clear for the pumps to keep the detritus suspended or pooled for easy cleaning and its sort of protected with the rock on the eggcrate.
