🌱 TNA Aquarium Soil – Small & Large Grain (3L / 9L)

Flexible, Plant-Ready Substrate for Shrimp and Planted Tanks

TNA Aquarium Soil is a nutrient-rich, clay-based substrate designed to support healthy aquatic plant growth and maintain soft, stable water conditions. Available in both fine grain (0.8–2 mm) and large grain (5–8 mm) formats, this soil creates a reliable base layer for aquascapes, shrimp colonies, and freshwater fish that thrive in slightly acidic environments.

Whether you’re planting delicate carpeting species or building a layout with stem plants and larger roots, TNA gives you options to customize your aquascape by grain size and bag volume.

🔍 Key Features

  • Small Grain (0.8–2 mm): Best for carpeting plants and fine-rooted species

  • Large Grain (5–8 mm): Ideal for stem plants, higher flow tanks, or layering

  • Nutrient-Rich Composition: Supports root development and long-term plant health

  • Softwater Friendly (~pH 6.5): Buffers pH slightly to encourage shrimp and plant vitality

  • Improves Clarity: Helps trap fine particles and support biological filtration

  • Stable Over Time: Holds shape and resists compacting or rapid breakdown

  • Multiple Sizes: Available in 3-liter and 9-liter bags to suit nano tanks or large scapes

💧 Water Chemistry Impact

  • pH: Buffers toward 6.5 (mildly acidic)

  • KH: May reduce slightly in softwater setups

  • Compatible with: Caridina, Neocaridina, softwater fish, and CO₂-injected tanks

  • Recommended Add-ons: Root tabs can be used to recharge nutrients over time

 FAQ

Q: Is this substrate safe for shrimp?
A: Yes — it’s commonly used in shrimp tanks due to its softwater-friendly buffering and clean structure.

Q: Do I need to rinse it before use?
A: Rinsing is not recommended by the manufacturer. However, we suggest putting all substrate in a small container and adding water to check for clouding before adding it to your tank.

Q: How long does it last?
A: Typically 18–24 months depending on your tank’s bio-load. After that, it can be recharged with root tabs like APT Jazz

Q: Which grain size should I choose?
A: Use small grain for carpeting and detail work, and large grain for general scaping, layering, or tanks with higher flow.
