Would anyone see a problem using a Diamond Black & blasting grit/ laterite substrate under Eco complete African substrate mix? I have kept africans for years and have started thinking about trying some plants with them. I would like my african tank to have a sand substrate for ease of maintenance. It will be a lower light 2 wpg? lightly planted non co2 tank. I am wondering what effect the mixing/ uprooting of the digging habits of the fish would have as the Diamond Black comes to the surface. Any PH issues or other problems with it being mixed with the argonite in the Eco mix?
