All pondkeepers look forward to the warm summer days and nights to enjoy the sights and sounds of their pond. To ensure your seasonal satisfaction, remember, this is an important time to keep the pond clean and clear to ensure the health of the entire ecosystem.

Here are a few tips to keep your pond healthy all summer long:
  • Algae control: To combat green water and string algae, consider an algae control treatment that is added directly to the pond water. Additionally, if heavy algae blooms are a problem, consider adding an ultraviolet clarifier (UV clarifier). Suspended, microscopic single-cell algae are so tiny that they pass through even the finest filter. A UV clarifier uses ultraviolet light to destroy the reproductive ability of algae. The dead algae then clump together in particles large enough to be removed by the mechanical filter.
  • Fish care: Feed fish smaller amounts of high-quality food particularly in the summer. Fish should only be fed one to three times a day, with only as much as they will consume in five minutes. Fish eat what they need to survive in various conditions, and as the water temperature rises to 77°F and higher, fish will consume less food in a given time. Remember, fish in hot water temperatures may not show an interest in food. When fish feed in extreme summer heat, their movement also uses more oxygen, which is problematic if there isn't a sufficient supply in the water. Therefore, feed in the early morning, at the coolest time of the day.
  • Water care: Raised pollutant levels are generally caused by overcrowding the fish, overfeeding, or under-filtrating the pond. Each leads to an imbalance between the number of fish and the amount of filter bacteria, which decompose fish waste. Once identified, these pollutant problems are relatively easy to overcome. A partial water change will immediately dilute the problem, giving you time to identify the cause. Remember to treat the water with a product that makes tap water safe with a product that makes tap water safe for fish by removing harmful chlorine and chloramines.
  • Aquatic plant care: Aquatic plants provide important shade, which reduces algae growth. Aquatic plants provide natural filtration too, which helps clean the water by consuming nitrates and keeps oxygen at healthy levels. Plants are very important to an overall healthy pond. To keep them looking their best, tend to them regularly by removing dead blossoms, leaves, and stems to keep the pond free of debris and decay. Additionally, aquatic plants need extra care to promote growth and beauty. Remember to fertilize your plants with a product that is in a tablet form and planted directly in the pot next to the plants' roots. This will minimize the plants' release of chemicals and nutrients that would ultimately encourage algae growth.
