Natural Color Volcanic Substrate Red 1-2mm 5kg

Warm-toned aquascapes are hard to pull off unless the substrate helps. Volcanic red ceramic soil at 1-2mm does exactly that, with a structure fine plant roots push through easily. Supplied in a 5kg bag for planted and tropical fish tanks.

Roots penetrate the material easily and spread right through the bed, which is what a planted tank needs from its floor.

Working out how much substrate you need

To reach a Two Inch (2") gravel depth in your fish tank, measure up and follow these three steps:

1. Multiply tank LENGTH by tank WIDTH in inches. Worked example: 47" Inches x 19" Inches = 893
2. Divide that figure by 10. Worked example: 893 / 10 = 89.3
3. Divide by 2.2 to convert to kilogrammes. Worked example: 89.3 / 2.2 = 40.5 KG REQUIRED

Rough guide for a 2" substrate / gravel depth

• 60cm / 2ft TANK = 25 kg
• 80cm / 2.6ft TANK = 30kg
• 100cm / 3.3ft TANK = 35 kg
• 120cm / 4ft TANK = 40 kg

Treat these as approximates - you may well want a deeper or thinner layer of substrate / gravel.
