BEFORE WE BEGIN:
Let's decrease evaporation.
DAY 2, 48 HOURS LATER:
Normal evaporation can be up to .25" per day on average for a non-heated pool running no excessive waterfalls or water features.
Therefore, you can expect up to .5" of water loss due to evaporation in a 48 hour test.
In Central Florida, we expect more evaporation in the cooler dry months. Especially on warm days and cool nights. Most pools will see ZERO evaporation during our humid Summers.
If it rains, just start the test over.
- If your results are just barely into the orange, we’d highly recommend retesting or reviewing the EXCEPTIONS section. Water loss of .25” per day on average is a general guideline.
If your pool is in any of the following situations, you will likely see more evaporation than your neighbors… possibly more than the .25” per day on average (all of these can significantly increase heat or exposure thereby increasing evaporation):
On a golf course
On a pond or a lake
Immediately adjacent to a large yard or open area
More than 25 feet from the house
