I've never done a dirted substrate tank before, but I'm giving it a shot due to the cost savings. Previously, I've used aqua soil or nutrient-based sand in my aquariums. This time, I'm trying dirt mainly for the cheaper cost. I'm a bit concerned about it leeching into the water column, so I plan to add a deep layer of gravel and sand on top of the soil. I know using just sand or gravel is fine, but I'd rather be safe.
My question is, which one should I put down first - sand or gravel? Any other tips or advice would be greatly appreciated. My tank's specs are 600mm x 400mm x 400mm, if that helps.
