100% NATURAL. Every owner of underwater pets knows that decorations and aquarium substrates not only look nice, but also affect the environment of our fish. That is why it should be ensured that most of them are natural. Not artificially coloured and looks natural. If the substrate is too bright, the light rays reflected from it may have a bad effect on the fish's well-being. Our gravel has a natural light shade and does not produce strong light reflections.
One of the whitest natural quartz found in nature. Please do not judge the sand colour while it is in the bag. The sand may have a light shade of grey colour but it will look different and much more attractive when illuminated in the aquarium. Our Silica is not artificially coloured, therefore it looks very natural.
Due to the water and heat treatment at high temperatures the substrate is clean, dry and ready to use. Will not require rinsing before use. After pouring out the substrate into the aquarium and covering it with water, a natural cloudiness may occur, which will disappear very quickly after starting the filtration. You can rely on our experience. Buy sand from companies that specilise in aquarium substrates.
