Pebbles and Cobbles

At Swell UK we have a great range of pebbles and cobbles which can act as fantastic natural substrate for your aquarium. They look great scattered around aquatic plants and can help to create a more natural feel among plastic plants.

The pebbles we stock won't affect the pH of your water. They are pre-washed and include no dyes, just pure stones. They won't give off any powder and so you don't have to worry about your water becoming dirty or cloudy.
