Onyx Sandâ„¢ is a naturally dark gray sand that perfectly complements and enhances the appearance of any aquarium. It supports optimal KH levels for freshwater planted aquariums. Although ideally suited to planted aquaria, it may be used in any aquarium environment. Onyx Sandâ„¢ is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as laterite are not necessary. Onyx Sandâ„¢ is not chemically coated or treated, and as a carbonate rich sand, it has a slight buffering capacity that may raise pH by 0.1 - 0.5 pH units (depending on source water characteristics). Onyx Sandâ„¢ is good for the life of the aquarium and need not be replaced.

Create a flawless, natural-looking foundation for your marine or reef aquarium with CaribSea Aragamax Sugar-Sized Dry Aragonite Sand. Also known as "oolitic" sand, this super-fine substrate (0.25 - 1.0mm grain size) is renowned worldwide for its incredible purity. It is intentionally engineered to be completely free of harmful impurities such as ash, metals, pesticides, and silica, ensuring a safe and pristine environment for your delicate fish and invertebrates from day one.
Beyond its stunning bright white aesthetic, this sugar-sized aragonite provides immense biological and chemical benefits. It naturally buffers your water chemistry by slowly delivering essential calcium, carbonate, and trace elements to maintain a stable, healthy pH. Because of its remarkably fine, smooth, and round grains, it is the absolute perfect choice for shallow static beds. It is incredibly gentle on soft-bellied bottom dwellers like rays and sharks, and it easily passes through the gills of sand-sifting gobies and invertebrates without causing irritation.

DOOA Tropical River Sand is a substrate for aquariums.
It is a natural product from rivers and thus doesn’t contain pices of corals. As a result the DOOA Tropical River Sand does not raise the hardness of the water.
This sand is especially interesting due to the natural colour and gives a natural look to the aquarium, as it includes different grain sizes.
Thoroughly rinse before applying on the ground of the aquarium.

Multimineral nutrient soil for freshwater aquaria
Building on its extensive knowledge of the natural habitats of the most popular aquatic plants, Dennerle has developed a humus-rich long-term mineral nutrient soil especially for aquariums. The plant is optimally supplied with all the nutrients it needs via the strong, widely branched rootstock. This allows the care of even sensitive species that are rather difficult to keep in the aquarium. Of course, Deponit-Mix does not contain any additional phosphates and nitrates – nutrients that can promote algae in excessive concentrations – and it is covered by the aquarium gravel as the bottom layer. Many years of practical experience show: Deponit-Mix effectively prevents algae plagues. The combination of depot nutrients, trace elements and clay minerals, which regulate the nutrient balance, always gives the aquatic plant roots the right amount of nutrients. Humic-rich natural peat slightly acidifies the soil and makes plant nutrients more available. Clay minerals, humus substances and soil bacteria are already active in the slightly moistened deponite mix. The bacteria are supplied with oxygen through the two holes in the lid. Also unique are the white activator beads, which provide full microorganism power right at the start like a bacterial filling station. Depending on the plant population, lighting and other fertilization, aquariums with DeponitMix can last up to 10 years.
