Natural Color White Aquarium Gravel 4

A bright base bounces light back up through the water and noticeably lifts a dimly lit tank. This 5kg bag of 4 - 6mm white gravel does that at a grade coarse enough for waste to drop through to the siphon.

High-quality throughout, it can go into aquarium fish tanks or vivariums, serve as a hobby and craft material, or be used for general gardening - it is ideal for brightening up plant pots.

Specification

• 4 - 6mm (gravel)
• Supplied in 5kg bag

Working out how much 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" 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 gravel.
