Use whenever ammonia levels rise - fast acting formula.
Tetra AmmoniaSafe Fish Pond Treatment quickly reduces the dangerous ammonia in your Fish Pond. Tetra Pond Ammonia Safe removes toxic ammonia that is bad for fish and helps remove ammonia that builds up if your Pond Filter is not working correctly. Tetra AmmoniaSafe reduces toxic ammonia, converting it to a non-toxic form that will still allow the filter to develop. Shake well before use. Add 50ml of AmmoniaSafe per 1,000 litres (220 gallons) of pond water. Use the dosing cap provided. For even distribution, mix the required amount in a watering can full of water, and pour over pond surface.
