New Tank: Sprinkle Volcanic Ash evenly into a thin layer over the bottom of aquarium. Any areas intended for planting, build up to double depth. Cover with your substrate of choice, for example river gravel, pebble or sand. Established Tank: Option for replanting – dig a recess in your substrate and carefully fill with Volcanic Ash and cover. Plant into it. Option for general mineralisation – push aside a small area of substrate and place Volcanic Ash. Cover with substrate.
