What's under your rocks?

[jallard]

Im setting up a 34g tank and am considering putting a piece of plexi glass on the bottom to protect the glass before I place my sand in. Is this a good idea? Or is it unnecessary.

I use egg crate. I don't think there is any need to protect the glass but egg crate keeps the rocks from sliding around which can cause rock slides.

I don't have anything under my rocks and have never had a problem. Then again I've never really been a big fan of anything that burrows or digs either. When your mounting corals though just be careful. If you apply too much force this can cause the rocks to slide, but this is pretty easy to avoid.

I used egg crate as well. I sleep better at night with it in there.

Glass for every tank I've had the past 23 years or so.

i put egg crate under mine. no idea if it helps or not, but as thegrun noted, it helped keep the rocks in place a bit.

Egg crate and pistol shrimp and ok there's a couple YWG's there too and many, many , many bristle worms.

So i decided to put a piece of lexan under the rocks, its just like thin white plexi glass. Its probably not nesessary but makes me feel better about the rocks on my glass bottom. With 3" of aragonite sand on top no one will know but me

A better idea is to drill your base rocks and add acrylic rod "˜legs' to keep them off the bottom. Detritus doesn't get trapped and fish & inverts have extra hiding places
