Can't Find Egg Crate Anywhere

[ian in Geneva]

Hello everyone,
Can anyone help me. I want to line the bottom of my tank before I add rocks (it will be a Malawi tank)
I have read a lot about Egg crate but I cant find anything like it in Switzerland.
Is there anything else i can use to protect my tank as I add large (ish) rocks?

search ebay for koi filter grid, its the same stuff and atually cheaper than the items labelled egg rate
