Aquarium Substrate creates a good solid foundation for your fish tank. Mainly choosing from gravel or sand, find a suitable look that will help to compliment the rest of your aquarium setup. Plants love a fertilized substrate, helping to maximize growth. Great for planted setups but with normal sand or gravel and liquid fertilizer, a lush tank full of plants can be achieved. Most gravels or sands are pH neutral, although sands like aragonite or coral will help to buffer the water for cichlid’s or marine fish. All our gravel and sand is 100% natural.
