Hikari CyroPro is a ready-to-use liquid treatment formulated to control parasitic infestations caused by anchor worm and fish lice. It provides strong therapeutic action without damaging biological filtration, making it suitable for ponds, freshwater tanks, and marine systems. Safe when used as directed, CyroPro offers a straightforward dosing process and is widely trusted for managing cyromazine-susceptible parasites. Designed for practical, routine use, the formula remains effective whether you are dealing with an initial outbreak or recurring issues. It does not harm fish, plants, amphibians, turtles, or mollusks commonly kept in ornamental ponds. However, it must not be used in systems containing crayfish or other cultured crustaceans. Why Choose Hikari CyroPro? Proven parasite control: Treats anchor worm (Lernaea) and fish lice (Argulus) effectively. Safe for filtration: Does not disrupt biological filtration or beneficial bacteria. Ready to use: No mixing, no complicated prep; simply dose and repeat on schedule. Broad system compatibility: Suitable for ponds, freshwater tanks, and marine aquariums. Gentle on aquatic life: Safe for fish, turtles, amphibians, and mollusks. Dosing Instructions Preparation: Start with new water or perform a minimum 25% water change. System adjustments: Remove carbon, UV sterilizers, and protein skimmers before dosing. Dose: Use 5 mL per 50 gallons of water, distributing evenly around the perimeter. Repeat: Dose every 7 days for at least 21 uninterrupted days. Before each dose: Perform a water change to refresh oxygen levels and reduce pollutants. After final treatment: Carbon, UV, and skimmers may be restarted. Water Treatment Notes Avoid sulfur/sulfite conditioners: They may reduce effectiveness and lower oxygen levels. Correct volume matters: Calculate true gallons after accounting for substrate and décor. Not for crustaceans: Do not use where crayfish or cultured crustaceans are present. Cautions DANGER: May be harmful if swallowed. Avoid contact with skin and eyes. In case of accidental exposure, flush with water for at least 15 minutes and seek medical attention for eye contact. Keep out of reach of children. For aquarium or pond use only. Not for human, veterinary, or food use. PRO TIP For best results, maintain strict 7-day intervals without interruption. Any missed or delayed dose resets the treatment schedule, and restarting ensures complete control of the parasite life cycle.
