Natural Color Aquarium Reef Marine Sand DRY 0.8-1mm 5kg

Getting a marine tank's pH to hold steady is far easier when the substrate is doing some of the work for you. Supplied dry in a 5kg bag, this 0.8-1mm aragonite buffers as it sits, keeping the aquarium around pH 8.2 - 8.3 and supporting the alkalinity level.

The source is naturally sustainable aragonite, and the grade is perfect for both marine and reef aquariums stocked with corals as well as fish.

This is a dry reef base for reef and marine aquariums: premium quality natural aragonite, high in essential elements. It has been collected from a non-polluted pure natural environment, promotes stability of pH and buffers alkalinity KH levels, and is easy to use with all marine fish and corals.

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.
