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.

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.
