Has anyone tried to use reed/sedge peat in their tank? I was looking at different products and local shops sell an aquatic substrate for backyard ponds that is made up of mostly reed/sedge peat. According to this website, this peat has a ph of 4.5 to 7. 4.5 is obviously too low for anything I'd grow, but Aquarium Science says that almost all submerged soils will balance out at 6 to 7 after six weeks. Which is fine if that holds true. My main concern is the cap not being fine enough and the peat leaching out giving the water a consistent brown haze even after months of water changes. I'd love to hear about anyone's experience.
