Question with eggcrate method
I have a question for how to do the eggcrate method of land elevation.
If you use eggcrate to stack up the land, the eggcrate is porous and allows water to flow in and out of it. But this is bad if you put fish in because they will swim in the eggcrate, and it's ugly. I'm trying to figure out how to "trim-out" the eggcrate so that water can still flow in and out, but fish can't.
I was thinking to attach wiremesh onto it, and then putting cork board on top of that. But leave the top or bottom (whichever is less visible) without the cork-bark on it, so that water can still flow through the mesh. It just really needs to not let fish in, but let water through.
This would make it really easy to hide the filter, heater, etc.
Does anyone have any advice? Also, what would you use to attach the mesh onto the eggcrate?
