Preventing anaerobic gas bubbles in a Biotope
Hi, I'm planning to make a semi-biotope for Endler's & Habrosus. The bottom will be layered: Eco-complete, then Pool Filter Sand, then Leaf litter. My question is will anaerobic gas bubbles in the sand layer be a problem or will the layer of Eco below it help prevent that? I plan to have a good amount of leaf litter, wood & seed pods, so moving around the sand would be difficult. Thanks.
