JBL Sansibar Natural Substrate For Freshwater & Saltwater Aquarium

Perfect hold for plant roots: substrate for freshwater and saltwater aquariums and terrariums. 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. Under gravel heating can only be recommended for medium-fine to coarse substrates because water circulation cannot really build up in very fine substrates. 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) Not really suitable for under gravel heating cables.
