Live Rock and Sump
I'm sorry to all, I know I promised an update like 2 weeks ago then didn't do it...
I guess my credibility is damaged
I'll make it up to everyone by doing a huge update.
My next steps were to plan the live rock structuring. I wanted to be able to keep jawfish and other burrowing animals. I was worried about them causing a rock collapse by digging out sand underneath the rock. At the same time, I didn't want the rock sitting directly on the glass for fear of pressure points causing the bottom to shatter. What I decided to do was build a superstructure of PVC pipe under the sand that would distribute the weight of the rock while keeping it off the glass.
The first thing I did was to build a flat structure that sat under the sand. Then I got to thinking that it would be nice to provide an elevated shelf for the live rock to sit on, allowing for huge caves underneath the rock for fish to hang out. I built it in sections.
Here is the entire setup assembled
The whole thing is just dry fitted, I didn't use cement. I assembled it in 3 sections then put it together in the tank. Here it is in the tank.
Then I got to thinking... what happens if I have to ever remove this pipe... I'm pretty much stuck emptying out the entire tank to get the structure out of there if I ever want to change anything.
So, I redid things a little, instead assembling 3 sections. That way I don't have to empty the whole tank to get things out.
