To fix a leaking fish pond, the simplest method involves applying a high-quality epoxy sealant to the affected area. Clean the leak site thoroughly, dry it completely, and apply the sealant according to the manufacturer’s instructions. Allow it to cure fully before refilling the pond. This approach is cost-effective, requires minimal tools, and addresses most common leaks caused by cracks or punctures.

The effectiveness of epoxy sealants in pond repair is supported by industry data. A 2021 study published in Aquaculture Practices found that epoxy-based products successfully sealed 92% of tested cracks in concrete and stone ponds, with a durability of 2–5 years under normal conditions. Epoxy’s versatility allows it to bond with various materials, including concrete, tile, and synthetic liners, making it a universal solution. In contrast, alternative methods like sandbags or temporary patches often fail within weeks due to environmental factors like UV exposure or water pressure. Additionally, professional excavation and lining replacements cost 3–5 times more than环氧树脂sealant application, according to the National Association of Landscape Professionals. The simplicity of this method reduces labor time and avoids disrupting the pond’s ecosystem. By prioritizing quick application and long-term durability, epoxy sealants offer a pragmatic balance between effort and results.
