JBL Sansibar Grey 5kg Substrate

• Perfect hold for plant roots: substrate with 0.2 – 0.6 mm grain size for freshwater and marine aquariums and terrariums
• Ideal for aquarium care: its fine granulation and density prevents mulm and other waste material from seeping in
• 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
• Not really suitable for undergravel heating cables

Ideal substrate
The substrate is an important part of the aquarium interior 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 definitely 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 plant roots approx. 6-8 cm).
