HAQUOSS H18 - CYANO F

Cyanobacteria in freshwater are tiny, bright green and/or blue algae that form an almost oily film everywhere: on decorations, gravel, and plants. Often, their "coat" contains many oxygen bubbles produced by the microalgae themselves or by normal biological processes in the substrate (decomposition of leftover food and/or dead leaves). Cyanobacteria are permanently present in aquariums and can never be completely eliminated, but they can be significantly reduced. Their growth, as with all algae in general, is encouraged by inadequate fertilization of the plants and/or when they grow poorly and very slowly. The onset of cyanobacteria growth is most evident when they are present between the front glass (which usually receives sunlight from windows) and the gravel itself. Another cause is excessively bright aquarium lighting in the presence of a "fertilized organic substrate," which, when exposed to strong light, tends to develop cyanobacteria more easily. It is recommended to cover the substrate with low, groundcover plants such as hemianthus or glossostigma. When cyanobacteria first appear, measure the pH, kH, NO3, PO4, and fe levels. If the first two values are too high or too low, because they are linked, check the amount of CO2 supplied by the dispenser and adjust if necessary. If the dispenser is not present and the CO2 concentration is low (perform the appropriate test), add Haquoss P8, carbon booster until it reaches the desired level. If nitrates and phosphates are high, add the appropriate resins Haquoss nitrator and Haquoss phosphator to the filter. If iron is low, add Haquoss P6, iron booster. After adjusting the chemical levels, immediately perform a couple of partial water changes of 10% per day, vacuuming up any patches of algae that appear, without breaking them up, with a special vacuum cleaner and using Haquoss DM1, conditioner and Haquoss DM2, alive during the operation. After the two water changes, on the third day begin the treatment with Haquoss H18, trying to maintain the water's chemical values as explained above. Reduce the aquarium's daylight hours by at least 50% during the treatment.

DOSAGE: Using the supplied syringe, spray 1ml of liquid on each remaining cyanobacteria nest (each ml treats 5-6 cm2 of surface). Caution: For each daily treatment, use a maximum of 5ml of product for every 25 litres of water. Turn off the recirculation pump during administration, check that the fish are calm and not breathing heavily. Otherwise, reactivate the recirculation pump, turn off the CO2 supply system, if present, and activate the aerator. Apply 3 or 4 times, every other day in the same spot. At the end of the treatment, perform a partial water change of 15% using Haquoss DM1, conditioner and Haquoss DM2, alive. At the end of each treatment, within 15 minutes, it is recommended to measure the pH and kH. If the values drop, turn off the CO2 system, if present, and increase the air supply via the aerator. If this is not enough, intervene with Haquoss D12 kH plus or Haquoss D10 pH plus depending on the need. However, the attenuation of cyanobacteria and their almost complete disappearance are very slow and it may take up to 15 days to see the effects of the treatment. Harmless to fish, plants, and crustaceans. Do not overdose and do not combine with other medicines.
