Polluted aquarium water can be attributed to various factors. Food and substrates increase the phosphate concentration in water, for example, and the release of organic substances causes severe yellow tint. If concentration levels of nutrients such as nitrates and phosphates rise too much in an aquarium, the ecosystem will be disturbed, stunting the growth of fish and plants and they may even suffer damage.

Using Tropic Marin® granules and active carbon can quickly improve the water quality and raise it to the optimum level. To this end, the granules act as a carrier medium, binding harmful substances, and thereby removing these easily and completely from the aquarium cycle.
