🪴 Perfect for Aquascaping
The rich black tone of Ocean Six Gravel provides a striking contrast against plants, driftwood, and rockwork, making your aquascape appear more vibrant and polished. The darker substrate also helps fish feel secure by reducing glare and reflection, which can calm shy or stress-prone species.

🐠 Functional Benefits

• Encourages the growth of beneficial bacteria, helping to maintain stable water conditions.

• Provides a secure base for live plants, decorations, and rocks.

• Suitable for bottom-dwelling fish, shrimp, and snails due to its smooth texture.

• Does not alter pH or water hardness, keeping your parameters stable.

💧 How to Use

1. Rinse the gravel thoroughly under running tap water to remove dust and transport residue.

2. Spread evenly across the aquarium base, creating a depth of 3–5 cm depending on tank size.

3. Add décor, plants, and water carefully to avoid disturbing the layout.

4. Regularly vacuum the gravel during maintenance to remove detritus buildup.

💡 Pro Tip:
Layering fine and medium grains can create a more natural-looking substrate and allow for better plant anchoring.

🌿 For Planted Aquariums
While Ocean Six Gravel does not contain nutrients by itself, it forms an excellent base layer for root tabs or nutrient substrates. It allows plant roots to anchor firmly while supporting a healthy, oxygenated substrate zone.

✨ Why Choose Ocean Six?
Ocean Six products are trusted for their durability, purity, and visual consistency. Each batch is carefully cleaned and graded to deliver a substrate that looks beautiful, performs exceptionally, and lasts for years without breakdown or discolouration.
