Keep your terrarium fresh, clean, and thriving with Josh's Frogs Horticultural Charcoal. Often called the "secret weapon" of successful vivarium builders, this high-carbon material acts as a natural filtration system, neutralizing odors and trapping impurities before they can harm your plants.

Why Your Terrarium Needs It:

• Natural Odor Control: As water cycles through your terrarium, the charcoal absorbs toxins and gases that can cause "sour" smells, keeping your setup smelling like a fresh forest floor.
• Improves Drainage & Aeration: When mixed with substrate, these lightweight chunks create air pockets that prevent soil compaction, allowing roots to breathe and thrive.
• Bioactive Foundation: In a bioactive enclosure, charcoal provides a massive surface area for beneficial microbes to colonize, supporting the natural nitrogen cycle.

Key Features:

• Pure & Safe: 100% natural horticultural-grade charcoal with no additives, chemicals, or starters—safe for plants, and also sensitive amphibians, reptiles, and invertebrates.
• Versatile Sizing: Small, manageable chunks that are easy to layer or mix into custom substrate blends like ABG Mix.
• Long-Lasting: Unlike organic components that decay, charcoal remains stable indefinitely, providing permanent filtration for your terrarium.

How to Use:

1. As a Layer: After adding your Josh's Frogs Drainage Layer, sprinkle a 1/2 inch layer of charcoal over the top. This ensures that any water sitting in the "false bottom" is filtered.
2. In a Mix: Add charcoal to your potting soil or orchid mix (approx. 10% of the total volume) to boost aeration and prevent root rot.

A 4 quart bag is the perfect amount for:

• a 10-gallon aquarium or a 12x12x18 inch glass terrarium. It provides a solid, functional layer across the entire floor.
•  an 18x18x24 inch enclosure (will provide a filtration layer of about 3/4 of an inch).
