The UK is FINALLY starting to see some sustained warmer weather; however, with that comes a few added pond complications. As the temperatures increase, so too does life in your pond, potentially bringing algae into play. Warmth, sunlight, and nutrient-rich water create the perfect conditions for algae to thrive, leaving you with murky water, blanket weed, and frustrated fish.
Fortunately, there are a number of effective ways to combat algae growth. At AquaLiners Direct, we stock a range of proven solutions from trusted brands like Evolution Aqua, Oase, Blagdon, and DyoFix to help you stay ahead of the bloom and with that, here are four steps for how you can beat the algae this pond season.
1. UV Clarifiers: Your First Line of Defence
One of the most effective ways to keep green water at bay is by using a UV clarifier. These devices pass water over a UV bulb that damages the single-celled algae responsible for turning water green, causing it to clump together and be easily filtered out.
- Oase and Blagdon offer powerful, easy-to-install UV clarifiers suitable for a range of pond sizes.
- Remember to replace your UV bulb annually for optimum performance—spring is the perfect time.
2. Water Treatments: Test First, Then Target Blanket Weed and Green Water
If algae have already taken hold, the first step should be testing your water to understand what might be fuelling the growth. High levels of nitrate, nitrite, carbonate hardness (KH) or pH imbalances can all encourage algae to thrive.
Once you understand what your pond needs, targeted treatments can help restore clarity and control algae. Products like Blagdon Green Away and Evolution Aqua Blanketweed Treatment are fast-acting, pond-safe options that break down algae without harming fish or plants.
- Choose treatments tailored to your specific issue—some work best against filamentous blanket weed, others are ideal for suspended green algae.
- Combine with water quality adjustments if needed (e.g. stabhttps://aqualinersdirect.co.uk/collections/pond-electricals-air-pumpsilising pH or reducing excess nutrients).
- Always check compatibility with your pond’s wildlife and follow dosage instructions carefully to avoid disrupting the ecosystem.
3. Shade and Light Control: Natural Prevention with DyoFix
Algae needs sunlight to grow. That’s where DyoFix Pond Dye comes in—a dye-based additive that reduces the amount of light penetrating the water without harming aquatic life. It’s a subtle yet powerful way to deter algae while maintaining a natural look.
- Easy to apply and long-lasting, DyoFix is ideal for ornamental ponds, wildlife ponds, and even larger lakes.
- The Dyes are manufactured to be safe for humans, animals, fish, amphibians and insects.
4. Improve Filtration and Aeration
Poor circulation and low oxygen levels contribute to algae problems. Upgrading your filtration system or adding an aerator ensures your pond stays well-oxygenated and free from stagnant areas.
- Products from Evolution Aqua and Oase can be combined with UV filters to create a complete algae control system.
- Keep your filters clean and check pump flow rates during hot weather.
Summary: Stay One Step Ahead
Algae is a natural part of any pond ecosystem, but it doesn’t have to take over. With a proactive approach and the right tools, you can enjoy crystal-clear water all summer long.
