Thank you for the interest. Where are you located in the world? Do you have a tank thread? Please link here, if you wish. For me, it provides a better platform for dialogue.
Weight on eggcrate has never been a problem on 25 year old Jaubert Plenum with > 6” sandbed plus large live rock on top of substrate.. After 25 years, my sandbed begin declining two years ago after a predator Wrasse decimated detrivores crew in substrate. Ten months ago, I vacuumed out several hundred pounds of aroggonite to reduce sandbed to < 2”. My project before New Years is to remove all live rock to catch Melnanarius Wrasse and allow detrivore crew to be reestablished. During this time, I will remove substrate to be lightly flushed out by well water with no chemicals. I will then plumb a 1/2” pvc manifold beneath eggcrate to support weight of substrate. The foundation support is drilled with equally spaced holes to distribute flow evenly. Fiberglass screening covers eggcrate and is tucked in next to glass and if possible underneath eggcrate and into void to hide loose ends. I found this difficult and unnecessary. Use substrate to hide eggcrate and fiberglass screen. Allow eggcrate spacing of 1” from glass edge. This allows ample space to place fiberglass screen material. After pouring substrate, use a thin flat edge to push screen back allowing substrate to hide screen & eggcrate. Diffused hydraulics is appropriate to discribe piping.
Consider flow as diffused. The most important thing is oxygen.
With reduced oxygen conditions, the bacteria populations schew to reducing chemistry. There is no need to encourage reducing chemistry in a healthy, mature reef tank.
This video is my 25 year old tank five years ago when GSP was ping pong size.
