Natural Color Aquarium Reef Marine Sand DRY 0.8-1mm 2kg

Nano reefs and small marine setups need their sand bed measured in kilos rather than sacks. A 2kg bag of dry 0.8-1mm aragonite is enough to cover a small footprint outright, or to top up a bed that has thinned over a few years of maintenance.

It suits both marine and reef aquariums holding corals as well as fish. Because the source is naturally sustainable aragonite, the sand helps hold your aquarium around pH 8.2 - 8.3 and supports the alkalinity level as it sits.

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.
