Above ground koi ponds act as a striking focal point in any garden, adding interest and sophistication to your outdoor space. Ponds fitted with glass viewing windows add that extra layer of excitement too as they not only enhance the aesthetic appeal of the pond but they offer you the opportunity to watch and enjoy your koi more conveniently, as well allowing you to monitor their health and behaviour.
Glass pond panels are undoubtedly an innovative feature and are growing considerably in popularity, but they do require regular cleaning and attention. Algae growth, environmental factors and weather conditions can all contribute to the accumulation of unwanted build-up, obscuring the view and potentially affecting the health of your pond's ecosystem. If left untreated, this growth and grime can become particularly difficult to remove.
So, what’s the best way to maintain pond glass and to ensure optimum visual clarity? Here, we will explore some tried and tested tools and methods for keeping pond glass clean and clear.
When should you clean your koi pond window?
We recommend cleaning your glass pond window as soon as you notice any algae build-up. If you keep on top of it, the job will be much easier. Some koi pond owners clean their glass panels as often as once a week in order to prevent a stubborn build up. If left for weeks or months, it will take considerably more effort to remove, and neglect may even cause staining or damage to the glass over time.
Tools for cleaning glass in shallow ponds
For shallow ponds, tools like telescopic brushes with soft bristles or algae pads are effective and affordable options. You can even opt for standard bathroom tile scrubbers with extendable poles, and apply some pond window cleaner. These tools allow you to reach the glass without getting wet.
You can use other household items such as kitchen sponges but there are a couple of things to be mindful of. Make sure your sponge isn’t too rough; opt for soft, non-abrasive sponges to avoid scratching the glass. Additionally, make sure your sponge hasn’t been used previously in the kitchen as it may contain cleaning agents that can harm your pond’s ecosystem. Always use pond glass cleaner solutions which are specially designed to keep your pond life safe.
Avoiding damage during cleaning
Avoid abrasive materials like steel wool or harsh chemicals, as they can scratch the glass and harm aquatic life. Always use gentle, pond-safe cleaning tools and solutions. Scratches in the glass may lead to increased algae buildup in the grooves, affecting water quality and the overall health of your koi.
Tips for Algae Prevention and Long-Term Clarity
Whilst algae is a natural part of a pond’s ecosystem, too much of it can reduce oxygen levels in the water and can impact visibility through your glass panel. For long-term clarity, there are steps that can be taken to reduce algae growth, naturally, and in turn, reduce cleaning frequency.
If you’re yet to install your pond, consider the following factors during the design process as to create the right conditions to deter pond algae from growing:
-
Positioning: Site the pond partly in light shade, not completely in full sun.
-
Sizing: Make your pond at least 60cm deep, if possible, to prevent the water warming up too quickly and causing more algae growth on your glass.
- Plants: Introduce plants like water lilies or hornwort to shade the water and compete with algae for nutrients.
By implementing these cleaning practices and preventive measures, you can ensure that your koi pond glass panels remain clear and your aquatic environment stays healthy. Regular maintenance not only enhances the beauty of your pond but also contributes to the well-being of your koi.
