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.

Pond Sludge Removerfrom Sera Sera Pond Sludge Rem over is an effective water care product for the biological decomposition of pond sludge and organic deposits. It supports the natural self-cleaning of the garden pond, improves the water quality and ensures a healthy pond environment for fish and plants. Product properties - at a glanceReduces pond sludge and organic depositsPromotes biodegradation through active bacteriaSustainably improves the water qualitySupports a stable biological balanceSuitable for garden ponds with fish stockingEasy to useFor clear and well-maintained ponds Sera Pond Sludge Remover has been specially developed to break down sludge, mulm and organic residues in the pond in a natural way. Leaves, plant debris, food residues and fish droppings accumulate at the bottom of the pond over time and can impair the water quality. The microorganisms contained accelerate the biodegradation of these deposits and relieve the pond ecosystem. This reduces oxygen depletion and improves the well-being of fish and plants. The Sludge Remover is particularly suitable for use in spring and summer, but can also be used regularly during the pond season if required. A useful aid for a clean and healthy garden pond. Zoo Roco tip Vacuum off coarse deposits before use and ensure a good oxygen supply in the pond. The combination with pond aeration enhances the effect of the Sludge Remover.

Acorus calamus – sweet flag for pond edges & shallow waterCaltha palustris is a classic spring-flowering plant for the garden pond and provides bright splashes of colour with its yellow flowers from March to May (III–V).

When the garden comes back to life after winter, it ensures a striking splash of colour by the water with its yellow flowers from March to May (III–V).

It fits perfectly at pond edges, in damp border beds or in areas that are permanently moist to wet. The recommended planting depth of 0 to –15 cm makes it perfect for the bank and shallow water edge zone: directly in damp soil at the edge or standing slightly in water. Marsh marigold looks especially beautiful when you plant it in small groups – this creates a calm, natural area that visually softens the pond edge.The delivery in a 18-cm pot makes it easier to plant and gives the plant a good root volume from the start. If you want a very clear pond edge or want to keep the position flexible, a planting basket is a practical solution: this keeps the marsh marigold stable in the desired spot and can be easily moved if necessary.Thanks to winter hardiness zone 1–2, Caltha palustris is suitable for permanent pond installations in many regions and is an uncomplicated choice for a low-maintenance, natural pond edge planting.Note on shipping: We make every effort to ensure that our plants arrive healthy and undamaged.

Zoo-Roco tip: Plant the marsh marigold where you often pass by in spring – it’s a perfect starting point for the pond season. If your water level fluctuates greatly in spring, place the plant in a planting basket at 0 to –15 cm so it stays stable and grows reliably.
