Buying advice

When choosing a pond liner, prioritize EPDM rubber for permanent, larger ponds due to its flexibility and 20+ year lifespan compared to cheaper PVC liners. Always calculate the surface area accurately and add extra depth to accommodate shelves and slope, and never skip the protective underlayment which prevents punctures from rocks and roots. For seals, ensure products are explicitly labeled as fish-safe or non-toxic to avoid harming aquatic life.
