  • Extra fast against strong algae growth
  • Ideal for floating algae (green water)
  • Reduces pH fluctuations
  • For clear ponds

Many garden ponds are heavily contaminated with algae, especially in summer. Nutrient-rich water, lots of light and warmth are crucial for this. The body of water becomes unsightly and at the same time poses a danger to its inhabitants: if there is a lot of algae, a lot of photosynthesis also takes place. The pH value varies greatly, which can be dangerous for fish.

SummerAlgaeStop has an active ingredient concentration and composition designed to combat extreme algae blooms in summer. The organism and metabolism of the algae are combated quickly and specifically. This counteracts the negative effects of strong algae blooms.

Our application and dosage recommendation

For optimal results, use in the morning. Dilute the dose with at least 20 times the amount of pond water (e.g. in a garden watering can) and pour evenly into the pond. Avoid contact of the undiluted product with aquatic plants.

When used properly, there are no known side effects on fish, plants and amphibians. Fish can remain in the pond during treatment.

For best results, if necessary, check the pH value before use PondFit set in the optimal range. This is suitable for checking pH rapid test from Söll.
