TM Aquatix Aquarium Gravel Natural White Fish Tank Sand Plant Substrate LIGHT SILICA 1-3mm 5kg

• Grain size: 1-3mm / Chemical composition: SiO2 99% (Silica)
• Suitable for every biotope and above all, perfect for plant aquariums. The right fraction favours the good rooting of plants. Safe for all living organisms. It does not influence water parameters, and does not change the Gh, Kh, Ph values.
• 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 Sand is not artificially coloured, therefore it looks very natural. Our observations show that every substrate in the aquarium is lighter. This depends mainly on the tank lighting
• 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.

In order to create a 4-5 cm thick layer of substrate in an aquarium of a given bottom length the following is needed: 30cm / 1ft = 5-7 kg 60cm / 2ft = 10-15 kg 80cm / 2.6ft = 15-20 kg 100cm / 3.3ft = 25 kg 120cm / 4ft = 30-35 kg 150cm / 5ft = 50-60 kg 200cm / 7ft = 80-90 kg
