Dosage: 6.8gms per 1000 gallons (4546 Litres) of pond water.
Do not use below 10°C (50°F).
Directions: Measure the correct dosage for your pond. Add to a bucket of hot water and aerate for 20 miniutes to gas off any impurities. Fill a clean watering can with solution from the bucket, slowly apply to the pond over a 1 hour period. This will prevent shocking the pond with a highly concentrated dose.
