Tetrapond Season Start

A pond does not restart cleanly after winter. Fish come out of the cold months with weaker immune systems, and a pond can carry too many nutrients and too little oxygen at exactly the point everything is trying to get going again - a combination that leads to poor water and algae before spring has properly arrived.

Tetrapond Season Start is a water-care liquid designed for that specific moment: the point of activating a pond after winter rather than routine maintenance through the rest of the year. It works by adding minerals, trace elements and B vitamins to the water, which Tetra describe as helping create healthy living conditions for pond fish and reducing excess phosphate to guard against algae growth. Its effect can be increased by running a water aeration system alongside it.

• Water conditioner for restarting a pond after winter
• Contains minerals, trace elements and B vitamins
• Tetra say it helps reduce excess phosphate (PO4), which feeds algae growth
• Effect can be increased with a water aeration system such as Tetra Pond APK 400
• Available in more than one bottle size

On dosing. Tetra tell you to follow the detailed instructions on the bottle, but that dosing schedule is not something we have been given, so we can't repeat it here - check the label for how much to add relative to your pond's volume.

Who it's for: pond keepers reopening a garden pond in spring who want a seasonal boost rather than a year-round dose, particularly if algae has been a problem in previous springs.
