I believe there may be an issue going on with the pool. We run our filter overnight and for the past 2 days I noticed the water level was lower then what it was the day before. So yesterday we ran a test - we filled the water level to the point it was supposed to be at last night - this morning when we woke up I would say it was a good 3/4 of a inch lower then it was the night before.
So my question is what could be some reasons or possibilities for this? Is there anything I can do proactively to begin eliminating possible things that could be wrong before I call in a professional?
All season everything went off without a hitch and now getting down to the end we are noticing this!!!
Thank you in advance for any guidance.
