    Water Evaporation

    That time of year when a lot of evaporation is happening.

    Wonder if there's a calculator for that?

    I'm bringing up the water level to the "right spot" about every third day. There are no leaks. I checked using the 5 gallon bucket method on the steps.

    No calculator... evaporation is dependent on many variables... humidity, cloudiness, wind speed, air temp, water temp, etc.

    "Shock" is a process, not a product!

    It is difficult to get an exact value for a particular day but you can get an average rate from this link. You can improve the estimate a bit by doubling the daily average for summer months and halving it for winter months.
