Who Gives A Fish Forums

Cheers lintel, think I'll steer clear of limestone then, water's already hard enough. Thanks for the heads up on using plastic grills at the bottom, that's a top tip to prevent scratching the glass.

Looks fantastic, gorgeous fish. That weathered limestone - love it. Got any idea where I can get my hands on some? Is it inert or does it mess with the gH? And egg crate - what's the story with that, is it just for stability or does it serve another purpose?
