Hi Teapot,

Well, I finally have the results of the 'bucket' test. In the pool water I lost about 2/3" of water over two days, which works out to 38cu ft. (if my calculations are correct. This is 284 US gallons or 236 imperial gallons.) In the bucket I lost 2/5" of water over the same period, 2 days. This is 178 US gallons. I estimate the surface area of the pool to be about 700 square feet. Does this sound like normally evaporation rate to you?

Thanks,

...... john
