My inground pool has several white spots on bottom where the paint has come off What is the best way to repair and could this be causing my pool to lose water It seems to have aleak somewhere also?

Do a bucket test to determine if there is in fact a leak. Put a bucket on the top step in the pool, add water to it to about the same level as the water level on the outside of the bucket. Mark both the inside and outside of the bucket at water levels. Within 12 hrs. check the water levels again. If they are both dropping at the same rate then you most likely do not have a leak. You can expect up to 1 1/2" per week evaporation. If the level of pool water has dropped more than the level inside the bucket then you may have a leak. A leak detection service will find your leak most likely within a few hours.

The white spots may indicate that you are loosing your plaster top coating. Also, is the pool painted or does it have a plaster finish. Possibilities for this are:

Improper chemical balance for long periods

Old plaster

Plaster that has been left dry for more than a few hours.

Bad plaster job if new plaster.

Blisters usually caused when the pool has been left dry for a few hours.

Bad acid wash if that has been performed within the last two years.
