PURE+ Filter Start Gel 1 litre is a live, concentrated bacteria culture for maturing new pond filters. The gel based solution sticks to any type of filter media, allowing the nitrifying bacteria it contains to rapidly colonise your filter. Once the filter media has been coated with PURE+ Filter Start Gel, the beneficial bacteria within the gel will speed up the maturation of your filter media, while helping to convert ammonia and nitrite, resulting in less stressed fish.

One litre of PURE+ Filter Start Gel may be used for up to 10,000 litres of pond water:

• PURE+ Filter Start Gel 1 litre is suitable for ponds up to 10,000 litres
• PURE+ Filter Start Gel 2.5 litre is suitable for ponds up to 25,000 litres

Dosing Instructions:

• PURE+ Filter Start Gel 1 litre may be used to treat up to a 10,000 litre pond (do not overdose as it depletes the oxygen in your pond)
• Always provide additional aeration to your pond via an air pump and diffuser when using PURE+ Filter Start Gel.
• Shake well before use to ensure the bacteria have not settled.
• Unscrew the cap and pour the contents of the bottle directly onto your filter media for best results.
• Always perform regular water tests using a suitable test kit, especially before adding fish to the pond.
