Brightwell Aquatics Florin Volcanit Rio Escuro-M
Overview
Brightwell Aquatics Florin Volcanit Rio Escuro-M is a medium-grain black volcanic ash substrate created for freshwater planted aquariums and shrimp biotopes. Its oblong, bead-like granules provide a natural dark riverbed look while gently lowering GH and nudging pH below 7, creating soft, slightly acidic conditions ideal for Caridina shrimp, soft-water fish, and rainforest-style planted tanks. The semi-open structure of the substrate bed supports strong root development, good water diffusion, and long-term stability.
Key Features
-
Medium black volcanic ash substrate with ~5 mm particles for a natural, river-inspired aesthetic
-
Gently binds hardness-causing ions, helping to lower GH and slightly acidify alkaline water (pH < 7)
-
Ideal for shrimp biotope aquariums, especially Caridina and other soft-water species
-
Provides an excellent rooting medium that promotes strong root systems and nutrient uptake
-
Semi-open structure enhances interstitial water circulation, helping keep roots oxygenated
-
Supports long-term health of plants, fish, and motile invertebrates that prefer soft, slightly acidic water
-
Durable, bead-like granules retain shape over time under typical soft-water conditions
