so I am still new to this. Have had my pool a month and this is the first time I have had significant rains. It's been raining non stop since Saturday. It's crazy how much dilution I have gotten. Is this normal? Here are my pre rain numbers:
I have added a little extra bleach after the first heavy rain as it dropped my FC to 6. Keeping it above normal during the rain seemed like a good idea.
i haven't tested CYA because with no bright sun I am sure it would be inaccurate but I am assuming that's dropped pretty good too. Anyways. I'm adding calcium and salt and it will be fine but it is normal to have that much dilution? Just today we had between 2-4 inches. I did drain some as well.
