PO4 phosphate is a residue from the degradation of organic matter such as food scraps, fish droppings, etc. It is likely to cause the proliferation of algae. Although it is preferable that the PO43- values ??are as low as possible, values ??of up to 0.5 mg / l are tolerable. Caution: Phosphate tends to form sparingly soluble salts, which are added to the bottom mud. So be sure to regularly remove the mud from the bottom of your aquarium. Keep out of reach of children.
