Brightwell Aquatics FlorinVolcanīt Rio Escuro-XF – Volcanic Substrate for Planted Aquariums & Shrimp Tanks – Lowers GH & pH – Supports Root Growth, 15lbs

Brightwell Aquatics FlorinVolcanīt Rio Escuro-XF is a premium volcanic substrate crafted for planted tanks, shrimp biotopes, and soft-water aquariums. Its unique composition lowers GH and pH, creating the slightly acidic, mineral-deficient conditions found in tropical rainforest streams and rivers. This high-porosity substrate supports strong root growth, nutrient uptake, and water flow within the substrate, preventing anaerobic conditions. Ideal for Caridina shrimp, discus, tetras, and other soft-water fish, it helps create a natural biotope environment that enhances fish and plant health. Unlike many substrates, FlorinVolcanīt Rio Escuro-XF does not require rinsing and gradually conditions the water over time. It pairs perfectly with FlorinBacter, FlorinMulti, and other Brightwell supplements to support a thriving planted aquarium.
