I want to set up a plenum with live sand and live rock. I have read in various books about using plastic eggcrate with fiberglass screen. I wanted to know if anyone has found a descriptive website and/or book on how to setup a plenum that I could be referred to.
For example, I wanted to know if 1" is adequete for the height of the plenum? What diameter PVC wsas used to support the eggcrate? How is the fiberglass screen attached to the eggcrate? Should the live sand be place on top of this screen or should some other substrate be used and then another fiberglass screen? If some other substrate is used for this first layer what should it be and how deep? How deep should the live sand be?
Thanks for any information.
