Swell Substrate

At Swell, we boast one of the biggest ranges of aquarium substrate anywhere in the UK, and because of our pricing, you can get Swell Substrate at better prices than comparable products elsewhere.

Swell substrates are of premium quality, just like many other name brands available on the market, but because we have it made up ourselves, we are able to keep costs to a minimum and pass the savings on to you in the form of the some of the cheapest substrate prices around!

For course gravels of amazing natural and spectacular vivid colours, to soft, find sands to help recreate and calm ocean scene, we have got it covered in our range of Swell substrates.

Our gravels and sands get their inspiration from all over the world, from Samonan sand, to Nordic gravel, allowing you to create stunning effects in your aquarium. Some types of Swell substrate will also help with your filtration, providing micro gaps in the sand or gravel where nitrifying bacteria can develop in colonies, helping to break down ammonia and other debris that falls to the bottom, and improve your water quality in conjunction with your filter system.

All bagged up and ready to fly off our shelves at Swell like they do every week, your order or substrate can be dispatched the very same day when you buy before 3pm weekdays.
