Most of the tropical substrates that we've seen in nature are comprised of soils, bits of plants, bark, wood fibers, and other organic materials, in addition to sands. WHY I LOVE IT: When I first formulated our coconut-derived substrate, Fundo Tropical, I utilized mainly coconut-husk material which looks, feels, and functions much like the natural substrate materials found in tropical streams and rivers.
