Swell Harlequin Gravel Blue is a vibrant coloured gravel that is epoxy coated so it won't go powdery like painted dolomite gravel which use powder paint and affect your pH.
Swell Harlequin Gravel Blue is a durable epoxy coated gravel in a striking navy blue.
Epoxy coating is preferable to painted dolomite gravel which use powder paint and can leave powdery residue and adversely affect your water's pH.
Harlequin gravel has grains of around 3-8mm long. Because of their striking colours they are perfect for a child's aquarium.
The coloured gravel is a glossy, vibrant shade that gives a really tropical look to your aquarium.
Best of all because Harlequin Gravel is part of Swell's own brand range it will save you money compared with big name brands.
Please note you may be advised to rinse the gravel briefly before adding it to your aquarium. Although it is powder-free, the nature of stones mean they can occasionally chip a little in transit, so this just ensures there are no undesirable little pieces of stone in your tank.
Nordic Gravel is available in two different size bags, 2.5kg and 5kg.
