Recommended use

River gravel 3-5 mm is especially suitable for freshwater aquariums where a natural and timeless substrate is desired. It works well in community aquariums with species such as tetras, barbs, gouramis, cichlids, livebearers and other fish that use the middle and lower areas of the tank. In planted aquariums, it can be used as a visible top layer or as part of the substrate structure.

Who is this product for?

This product is suitable for aquarists who want a natural, calm and easy to maintain aquarium bottom. River gravel is a good choice for beginners setting up a first aquarium and for experienced hobbyists building a clean, natural and long lasting aquascape.

How to use

Rinse the gravel thoroughly before adding it to the aquarium to remove transport dust and loose fine particles. Spread the gravel across the aquarium bottom to the desired depth. A thinner layer at the front and a deeper layer at the back can create a better sense of depth and provide more planting space.

Substrate depth and coverage

The coverage of a 20 kg package depends on the aquarium footprint and desired substrate depth. In planted aquariums, it is often useful to create a deeper substrate layer toward the back and in planting areas. If the aquarium contains driftwood, rocks or terraced structures, the gravel should be arranged so that the layout remains stable.

Before use

Always choose substrate according to the needs of the fish species. If the aquarium contains very sensitive bottom fish with delicate barbels or fish that dig heavily in the substrate, finer sand may be a better choice in some setups. However, 3-5 mm river gravel is a versatile option for many aquarium layouts when livestock requirements are considered.
