Hello! I want to ask what impact will it have if I use Seachem Meridian Sand to create a river in my aquascape. Will it raise my PH too high? I am currently using ADA Amazonia Aquasoil for the rest of my aquascape and my tap water parameters are: PH: 7.4 KH: 1° GH: 2° My plan is to grow plants such as jave fern, ludwigia, anubias nana with a dwarf hair grass carpet and to have some cardinal tetras and rainbowfish. I also have some pool filter sand on hand if I can't use the Meridian. Thanks.
