Florin Volcanit Rio Cafe-F - FAQ

What is FlorinVolcanit Rio Café used for?
FlorinVolcanit Rio Café is a natural volcanic ash substrate designed for freshwater planted aquariums and shrimp systems, providing a stable base for plant growth and aquatic life.

What are the benefits of using Rio Café as a substrate?
It supports strong root development, enhances nutrient uptake, and promotes long-term plant health while helping maintain stable aquarium conditions.

How does Rio Café affect water chemistry?
It binds elements that contribute to hardness, lowering general hardness and slightly acidifying water to a pH below 7.

Is Rio Café suitable for shrimp aquariums?
Yes, it is ideal for shrimp biotope aquariums, especially species that thrive in soft, slightly acidic water conditions.

Can Rio Café be used for planted aquariums?
Yes, it is specifically designed to support rooted aquatic plants by improving oxygenation and nutrient delivery to roots.

What type of material is Rio Café made from?
It is composed of natural volcanic ash formed into durable particles that maintain structure while supporting plant growth.

Does Rio Café help lower GH in aquariums?
Yes, it actively binds minerals that increase hardness, helping create low-GH conditions suitable for many freshwater species.

How does Rio Café support plant root systems?
Its structure allows increased water movement through the substrate, improving nutrient access and keeping roots oxygenated.

Do you need to rinse Rio Café before use?
In most cases, rinsing is not required before placing it in a new aquarium, though minor natural debris may be present.

Can Rio Café be added to an aquarium with water already in it?
It is best added to an empty aquarium, as adding it to a filled tank may cause temporary cloudiness.

How should an aquarium be filled after adding Rio Café?
Water should be added slowly to avoid disturbing the substrate, allowing for planting and proper layout setup.

Does Rio Café work with aquarium supplements?
Yes, liquid supplements and nutrient solutions can be used effectively due to the substrate’s open structure and water flow properties.

How long does Rio Café last in an aquarium?
The substrate maintains its structure for extended periods, though its effectiveness may decrease over time depending on water chemistry.

Can Rio Café be used with undergravel filtration?
No, it is not recommended for use with undergravel filtration systems.

What type of aquariums benefit most from Rio Café?
Aquariums replicating natural river or forest environments, including planted tanks and shrimp setups, benefit most from its properties.
