Aquarium Advice Regular
Alright, so I'm not sure if this is in the right forum, I apologize if it isn't. Anyway, a few days ago I decided that I wanted to switch my white sand to black as I think it would look better. Now that I've found the substrate that I'm going to use (black crushed granite grit), I'm wondering exactly how to prepare and execute this so it's as easy on my fish and biological filter as possible. So if you have done this before any advice would be appreciated! Cheers!
