Yep, you have the right idea. As you are placing the rock, add water to the tank to just cover the largest rock (if it isn't already full). This will take the pressure off the contact points.

Why not use egg crate? I imagine it would be cheaper than acrylic.

I prefer eggcrate for this too but a piece of acrylic will work too

well, eggcrate at least allows water flow through it. i worry that the plexiglass will warp a little under the weight of the rock, and allow debris and anaerobic bacteria to build up underneath. that would be a time bomb for the tank.

I already have the Plexiglass and a piece of acrylic but i just wanted to make sure before i put them in. So is it alright or not??
