- Optimal grain sizes: hese substrates provide excellent root anchorage and a comfortable surface for bottom-dwelling species such as cory catfish and armored catfish.
- Promotes vigorous plant growth: when combined with nutrient-rich bases like JBL AquaBasis or JBL AquaBasis plus, these substrates prevent sludge infiltration and allow plants to absorb essential nutrients effectively.
- Fish and invertebrate friendly: fine granite sand and natural granules are gentle on sensitive barbels and do not release unwanted pollutants into the water, creating a healthier habitat.
- Visual enhancement: substrates with no light reflections help shy or easily stressed animals feel more comfortable, showcasing their full, natural coloration for a stunning aquarium display.
- Compatibility with heating systems: select substrates with coarser granulation are well suited for undergravel heating cables, while finer substrates are recommended without undergravel heating to ensure proper water circulation.
Rinse the substrate thoroughly with tap water to remove any transit abrasion. For optimal plant growth, apply the substrate over a nutrient base at a depth of approximately 6-8 cm. Calculate the required amount using the formula: aquarium length (cm) × width (cm) ÷ 140 = kg substrate for a 5 cm layer thickness.
