Okay, now that we have some benchmarks put together it is time to relate this to your pond losses. In the calculation we included two outcomes, sheltered and open ponds. If your pond or water feature is in a shady area or doesn’t get a lot of wind, utilize the SHELTERED range. If its Sunny or windy, use the OPEN range. If it’s anywhere in between or close to either of these ranges, chances are you don’t have a leak. If it does go above this please Contact Us and we can further guide you!
