Description
ZERONITRA DOLCE Nitrates derive from the decomposition of food residues, plant remains and fish waste. They are the end product of the nitrogen cycle. Since plants typically remove only a small fraction of the nitrogen produced in the aquarium, nitrates can accumulate quickly. Excess nitrates promote algae growth that, in addition to being unaesthetic, can hinder plant growth. In high concentrations, nitrates become dangerous for the health of aquarium fish. ZERONITRA eliminates nitrates in 48 hours and keeps on working to maintain the minimum level. ZERONITRA effectiveness depends upon on the amount of nitrate initially present in the aquarium, and the rate at which new nitrate is produced by the biological filter. That rate depends upon the fish population, feeding rates, and filter efficiency. For this reason, we advise periodic testing for nitrate to determine the optimum schedule for product replacement. It does not alter pH and is not hazardous for aquarium fish or plants.
ZEROPHOS DOLCE Phosphates derive from the decomposition of food residues, plant remains and fish wastes. In small amounts, phosphate is necessary for plant development, but an excess promotes the proliferation of algae. Apart from being unattarctive, algae can hinder plant growth. ZEROPHOS eliminates phosphates in 48 hours and keeps their level at an adequate concentration for plants. ZEROPHOS effectiveness varies, depending upon the amount of phosphate initially present, and the rate at which new phosphate is produced by decomposition. This, in turn, depends upon the population density and on the efficiency of the filter system. For this reason, we advise checking the level of phosphates periodically to determine the optimum schedule for product replacement. ZEROPHOS does not alter pH and is harmless to the aquarium’s inhabitants. It also reduces the amount of silicates dissolved in the water.
