• Perfect hold for plant roots: substrate with 0.2 - 0.6 mm grain size for freshwater and marine aquariums and terrariums.
• Vigorous plant growth: prevents the seeping in of sludge and other waste material with its fine granulation and density.
• Ideal for fish, invertebrates and plants: no release of unwanted pollutants into the water. Fine granite sand is gentle on the sensitive barbels of the bottom-dwellers.
• No light reflections – full colouring of plants and fish: easily scared animals feel more comfortable and show their full, natural colouring.
• Contents: 1 bag Sansibar Dark. Not really suitable for undergravel heating cables.

PRODUCT INFORMATION

Ideal substrate:

• The substrate is an important part of the aquarium components because a lot of animals dig in the ground to search for food.
• The plants also need a safe hold and have to absorb the food in the ground through their roots.
• Digging fish absolutely need a substrate which is not sharp-edged.
• Undergravel heating can only be recommended for medium-fine to coarse substrates because water circulation cannot really build up in very fine substrates.

Use:

• Rinse the substrate with tap water to remove any abrasion caused in transit. Put substrate on the nutrient substrate (JBL AquaBasis) to promote the plant growth (for vigorous growth about 6-8 cm).
• Calculation formula
• The right amount of substrate: length (cm) x width (cm) : 140 = kg substrate with 5 cm thickness.

FAQ

Are the substrates of the Sansibar range plastic-coated soils ?

> No, the substrates of the Sansibar range are not plastic-coated but pure natural products.

Should JBL Sansibar be washed before use inside the aquarium ?

> JBL Sansibar comes pre-cleaned. To wash out any abrasion caused in transit, we recommend rinsing JBL Sansibar before use in the aquarium. Please avoid unsettling the soil when filling in the water.

Can JBL Sansibar black also be used for aquariums with shrimps and other invertebrates?

> Yes, this is no problem. The mineral composition of the natural product doesn’t contain any substances which are harmful to aquatic invertebrates.

On JBL Sansibar dark / grey we noticed a magnetic component. What is this?

> JBL Sansibar black is a natural product which has small fluctuations in its mineral composition depending on its source. The "magnetic component", which can be traced to iron cores, occurs in isolated cases, but does not have any harmful effects on the operation of the aquarium.
