Description
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.  The perfect natural sand for your planted or freshwater hardscape.
Features:
-
- Substrate with 0.8 mm grain size for freshwater and marine aquariums and terrariums
- Prevents injuries of the mucous membrane: coarse-grained, round-shaped natural sand is gentle on sensitive barbels. Ideal for digging fish, such as rays, kuhli loarch, catfish, etc.
- Ideal for fish, invertebrates and plants: no unwanted pollutants released into the water.
- Use: Spread substrate on top of the nutrient substrate (approx. 6 – 8 cm for plants). Well suited for under gravel heating cables
