i drilled my rock and used plastic rods ( they were the adjuster for blinds)
and it worked well but very hard to do with live rock took forever cuz it made a mess of the water with base rock it would be much easier because it doesnt need to stay wet

also the first time i used eggcrate................once your powerheads push your sand around a little bit and exposes the eggcrate it looks horrible not a problem with a deep sand bed but I only had 60 lbs in a 4x2 footprint so its pretty thin


when i moved and redid my rockwork no eggcrate and just stacked rocks so they were stable. I threw probably 1/4 of my rocks into my sump to create move open water in DT and I'm much happier.
