Brightwell Aquatics FlorinVolcanīt Rio Escuro-F – Volcanic Substrate for Freshwater Planted & Shrimp Aquariums – Boosts Root Growth, Lowers GH & pH, 15lb

Brightwell Aquatics FlorinVolcanīt Rio Escuro-F is a premium natural volcanic ash substrate designed to support freshwater aquatic plants, freshwater fish, and motile invertebrates like shrimp. Ideal for aquariums with slightly-acidic, low-GH water, it helps create an environment similar to rainforest streams and rivers. Its oblong, durable beads promote strong root growth by improving water flow and oxygenation within the substrate. This enhances nutrient uptake, ensuring healthy plant development. FlorinVolcanīt Rio Escuro-F gradually lowers general hardness (GH) and stabilizes pH levels below 7, creating optimal conditions for species that thrive in softer, acidic waters. Its semi-open structure supports water diffusion, allowing liquid supplements to reach plant roots effectively. This substrate is perfect for shrimp biotopes, fostering natural habitats while supporting plant and fish health. Compatible with various freshwater setups, FlorinVolcanīt Rio Escuro-F is a reliable choice for long-term aquarium health.
