- 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 unwanted pollutants released into the water. Fine, round-shaped granite sand is gentle on sensitive barbels of bottom-dwellers.
- Use: spread substrate on top of the nutrient substrate (approx. 6-8 cm for vigorous plant growth)
- Contents: 1 bag Sansibar White. Not really suitable for undergravel heating cables
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.
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).
