## Key Features

- • **Long-Term Durability:** Firm yet pliable substrate beads maintain shape and function for years, ensuring consistent water chemistry.
- • **Perfect pH & GH Balance:** Gradually acidifies water and lowers hardness to under pH 7, ideal for sensitive shrimp and fish species.
- • **Optimized Root Nutrition:** Creates a stable growth medium that promotes strong, oxygenated root systems for lush aquatic plants.
- • **Biotope-Ready Environment:** Designed specifically for freshwater shrimp and rainforest stream inhabitants, fostering natural health and vitality.
- • **Natural Volcanic Ash Powerhouse:** 3mm fine particles mimic rainforest riverbeds for authentic biotope aquaria.

## Overview

Brightwell Aquatics FlorinVolcanit Rio Escuro-F is a 15 lb fine black volcanic ash substrate designed for freshwater shrimp biotope aquaria. Its 3mm particles naturally lower water pH and general hardness, creating slightly acidic conditions ideal for rainforest stream species. This substrate supports strong root development in aquatic plants by providing a nutrient-rich, oxygenated growth medium, while its durable volcanic ash beads maintain stability and water chemistry for long-term aquatic health.

## Description

In forested and low-relief riverine habitats nutrient concentrations in the water column tend to be poor the bulk of the nutrient pool existing within the substrate composing the river bottom these nutrients are present primarily as a result of the continuous deposition of mineral- and organic-rich sediment being carried from upstream and from run-off Water chemistry in such riverine habitats tends to be slightly-to-moderately-acidic and generally low in concentrations of the elements that contribute to general hardness ("GH") Plants endemic to these habitats which constitute the majority of species commonly maintained in planted aquaria obtain a considerable percentage of their nutrient requirements through their roots it is therefore sensible to utilize a growth medium in planted aquaria that facilitates delivery of nutrients to the roots themselves as doing so encourages strong root growth and long-term plant health Maintaining plants fishes and motile invertebrates (such as the various species of shrimp that are maintained in biotope aquaria and as algal grazers) endemic to these habitats in water chemistry conditions specifically in terms of pH and mineral content similar to those that they have evolved in is also sensible and is likely to have a positive impact on their collective health FlorinVolcanīt Rio Escuro-F is a natural volcanic ash that has been formed into particles resembling oblong beads The beads themselves are firm yet pliable and are sufficiently durable to retain their shape for one or more years depending upon the specific water chemistry in the system Rio Escuro-F gradually lowers GH and pH to create conditions conducive to long-term husbandry of plants fishes and invertebrates endemic to most rainforest streams rivers and pools

## Features

- Ideal for use as a substrate in shrimp biotope aquaria 3mm particle substrate
- Natural volcanic ash with beneficial properties for aquatic plant growth and long-term care of fishes and motile invertebrates requiring slightly-acidic low-GH water conditions
- Binds elements that contribute to hardness lowering general hardness and resulting in a slight acidification of alkaline water to a pH of less than 7
- Used as a primary substrate forms the basis of a stable growth medium for rooted aquatic plants by permitting development of strong root systems encouraging nutrient-uptake through roots and allowing roots to remain sufficiently oxygenated
