sera Pond UV BlockerThe sera Pond UV Block er reduces the UV light transmission in the pond with concentrated humic acids. When used regularly, this ensures naturally clearer water, reduces green clouding and protects pond inhabitants through a shading effect - ideal in strong sunlight.Highlights: Reduces UV light transmission in pond water (humic acids)Reduces turbidity / "green water" by shading out lightInhibits excessive warming - especially in shallow water zonesCares for sensitive fish mucous membranes thanks to natural humic substancesSuitable for koi, goldfish & native species Strong sunlight can quickly become a problem in garden ponds: UV radiation promotes turbidity (e.g. greenish water due to floating algae), stresses fish and causes the water to heat up much faster - especially in shallow areas. The sera Pond UV Blocker provides a natural remedy here. The concentrated humic acids/humic substances it contains reduce the UV light transmission of the pond water. This creates a shading effect that can contribute to natural clarification when used regularly. At the same time, the pond inhabitants benefit: the lower light input can reduce the stress level and the humic substances support the care of the sensitive mucous membranes. Where is the UV blocker best used? Ponds with full sun or little natural shade Ponds with koi/goldfish or higher stocking levels Natural and ornamental ponds in which you want to avoid chemical intervention as far as possible (maintenance support)Application & dosage Dosage: 50 ml per 1,000 liters of pond water. Recommendation: dose weekly. In case of very strong sunlight / high turbidity: increase dosage to 2× per week.Application instructions: Shake well before use.Ensure even distribution (e.g. pre-dilute in a watering can or pour into the flow area). (Practical tip; manufacturer refers to "sufficient water movement" for distribution). Range of the variants: 500 ml → up to 10,000 L 2.5 L → up to 50,000 LIngredients / active principle Basis: Natural humic substances / (concentrated) humic acids Effect: Light filtering/shading, thus less UV input, supports natural water clarification with regular useFrequently asked questions:Does the UV blocker turn the water brown? Humic substances can give the water a slightly amber-colored, natural hue - similar to many natural waters. This is intentional because it filters out UV light. (Common humic substance effect; the "reduce UV light transmission" is the manufacturer's specification). Can I use the UV Blocker together with UV-C clarifiers/filters? Yes, it is generally common to use it with filter systems. UV Blocker works by filtering light in the water; filters then remove particles/clouding. (Combination note without hard manufacturer's exclusive claim.) Which fish is itsuitable for?For goldfish, koi and native fish species. How quickly will I see an effect? The product is designed for regular use and supports natural clarification. Visible changes depend heavily on sunlight, nutrient input and filtration.
