should i worry about putting anything under the sand?

Should i be putting anything under my sand? Im scared a peice of rock my fall and break the glass.

I was thinking of either using eggcrate or arcylic.

I used egg crate under mine and put my first layer of rocks directly on it then built up from there so that none of the sand burrowing creatures could cause a topple.

doesnt show through the sand?

I have a sheet of acrylic under each of my structures. If nothing else, it at least provides relief from those sharp rocks and preassure points on the glass. I'm sure the glass could take it but like you I'm paranoid like that :lol:

Actually, it was handy to have the sheets of acrylic underneath while I was in the process of aquascaping. This way I could slide the sheets around easily with rocks/bolders and all.

I wish I had the forethought to place a sheet of egg crate under my rocks. I have several fish that like to move my sandbed around and some egg crate would help to keep at least some of it in place over the bottom glass so that I didnt have bare spots. Plus reducing pressure points created by the rockwork would help me sleep better at night.

No, I covered it up with 3" of sand.

+1 on using eggcrate.

It's a cheap, easy way to add some peace of mind. You'll have plenty of other stuff to keep you up at night :wink:

what happened to cheap?!
the stuff was 16 bucks for 2x4

That is 1 of the cheapest things you will ever find in this hobby.

i made a base using pvc pipes and elbows and tees,then i zip tied some white landscapers cloth to the pvc(3/4" spaced 2" apart) this also keeps the sand above the glass
