How to Use
As with all pond treatment products pick coolest time of day to apply. DO NOT USE on very hot days. Ensure your pond has adequate dissolved oxygen (8-10 mg/l dissolved oxygen). Remove any dead algae that floats to the top as it occurs. Hydra Crystal requires an external filter to remove the treated algae. Do not use if your water does not have a green tinge as Hydra Crystal needs single cell algae to react with
Clean mechanical filters before starting treatment and keep these filters clean during treatment. Use when water temperature is above 12°C (54°F), i.e. not in winter months. Dilute with tap water (not pond water) and add as a slurry, add to pond near pump outlet so the product is totally mixed into the water, circulate water for even mixing and distribution. Leave UV and pump switched on.
During treatment ensure optimum dissolved oxygen in pond. Use aeration by water pump or air pump, remember algae is adding oxygen to your water, therefore removing it will lower water oxygen level. When treating allow plenty of time to observe fish in case of adverse reaction (increase oxygen levels in water if required).
DO NOT MIX with any other product. Do not use when temperature is below 12°C (54°F). Second Application (if necessary after 48 hours). Do a 10-20% water change before re-applying at same rate.
