## Description

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.

## 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
- When 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

## Questions & Answers

**Q: Can i use this product for south american chiclids?**
A: I don’t think this will be good for chickid, substrate helps to buffer your water to 6ph, I believe chiclids prefer a higher ph than that

**Q: Is the 5 lb bag enough for 10 gallon?**
A: yes

**Q: 2lbs good for 3 gallons?**
A: Yes, with prob half over,  unless your plan on keeping live plants, then you might wanna use more. But 2lbs will get it done.

**Q: Anyone else have this stuff turn to dust as soon as it made contact with water?**
A: I have the fine.  It didn't turn to dust.  Don't try to prewash it.  Just put it in the tank.  If you poor water gently onto bubble sheet or the package wrapper that helps not stir up the dirt.  It settled in less than 2 days, then I started my filter.
