Pond Bacteria That Fights Throughout Winter!

Winter is a time when people usually turn off their pumps, stop feeding their fish, stop adding pond bacteria and forget about their ponds until the spring. We retreat inside to the warmth, indulge on food and drink and forget about the pond that we cared for so dearly, only two months ago.

Whilst this seems like the logically thing to do, as not much happens in the pond over winter, it also makes your job a lot harder come spring. Debris begins to build up in the pond and begins to break down, leaching out organics and algae spores in to the water. These algae spores lay dormant until the temperatures rise above 8°C, where upon they have the perfect conditions to explode in growth. They have warmth, a food source from the deposited debris and most importantly no bacteria to fight with.

Winter Pond Treatment contains large amounts of our innovative bacteria that are capable of working as well at 4°C as they would at 14°C to digest the algae spores and unwanted organics that enter your pond during winter. Unlike other winter pond bacteria, our bacteria are strong at 4°C and will work below this, down towards 0°C to ensure you don’t suffer from an algae bloom or green water in spring.

By using winter pond bacteria in conjunction with a good winter preperation program, you can still turn off your pump, forget about your pond and indulge on food and drink, knowing that someone, or something, is taking care of the problem. Winter Pond Treatment contains no chemicals and is safe for all fish, wildlife and filters.

The Serious Bits

Ensure that pH level is between 7.5 & 8.5 and KH level is above 5 before using any bacterial treatment to get the most from the treatment.

When winter has passed, consider using Pond Klear to maintain pond health and keep green water at bay. Bacteria are a living organism and like any living organism, they only have a certain lifespan. Once this lifespan has been reached, they die and need to be replaced, so it is important to add bacteria in to your pond all year round.

  • Clean out filters & turn off UV light for 7 days during treatment.
  • Remove any surface algae/debris where safe & practical.
  • Use 1 tablet per 5,000 litres/1,250 gallons of pond water (for initial use we recommend a double/triple dose and then treat every 14 days).
  • BREAK/CRUMBLE tablet into bucket of pond water, stir and leave for a minimum of 2 hours.
  • Stir again.
  • Distribute evenly over pond surface.
