Is fish tank gravel safe for all fish?

Rounded natural gravel is safe for most freshwater fish. Avoid sharp or angular chippings for bottom-dwellers.

Do I need to rinse the gravel before use?

Yes — rinse to remove any residual packing dust, even though the gravel is washed before packing.

What size gravel is best for a planted tank?

2–4 mm or 4–8 mm allows plant roots to anchor without compacting too tightly.

Does natural gravel change water chemistry?

Quartz and most rounded pebbles are inert. Marble and limestone can raise hardness slightly over time.

Can I get custom retail bags?

Yes — we pack to your bag weight, jar size or pouch specification with your artwork.

How much gravel do I need for my tank?

Send the tank dimensions and desired depth and we will calculate the weight needed.

Do you supply samples?

Yes, we send sample sets or batch photographs before loading.

What is the minimum order?

One 20 ft container, split across colours and sizes.

Why rounded gravel matters in aquariums

Rounded gravel does not scratch glass or injure bottom-dwelling fish. Angular chippings can trap food and waste in sharp corners, making cleaning harder. For aquarium use, always specify rounded, washed stone.

Colours that sell

Natural white, black, mixed and honey tones are the staple aquarium colours. Bright dyed gravel is common in low-end retail but many specialist stores prefer natural stone that will not fade or leach.

Size selection by tank type

2–4 mm suits planted tanks and small fish. 4–8 mm is the standard all-round aquarium gravel. 6–10 mm and 8–12 mm work for larger tanks and cichlid setups where bigger substrate is preferred.

Washing and water safety

We wash aquarium gravel to remove dust, fines and any residual quarry material. The stone is inert and will not alter pH or hardness significantly. Rinse again before use to remove any packing dust.

Retail packaging

Aquarium gravel sells in 2–5 kg retail bags, jars and printed pouches. We can pack to your retail format with your branding, or supply bulk for local repacking.

Coverage per tank

A typical planted aquarium needs 5–8 cm of substrate depth. As a guide, 10 kg of 4–8 mm gravel covers roughly 60–70 litres of tank bottom at that depth. Send tank dimensions and we will calculate the required weight.

Batch consistency for retail

Aquarium customers often return for matching gravel to top up or set up a second tank. We retain a reference sample and batch code for every shipment so reorders match the original colour.

Freight and container payload

A 20ft container of mixed aquarium gravel sizes typically carries 25–27 tonnes. Mixed containers with other natural stone products are common for aquarium suppliers expanding into decorative stone.

Wholesale, bulk and export details
