i run a route for about 30 pools in alabama havent had to many issues all year but recently we had a bad storm about 5 days ago and it caused about 6 of the 30 pools to turn green in their own ways and im confused as to why all the chems are good and check them on a weekly basis but honestly very confused on why this happens when it rains specifically
 
A 6 inch whopper of a storm will only dilute a 60 inch average depth pool by 10%, as long as it's good and mixed.

If the FC is that low that 10% matters, it's not the rains fault.

If 0 FC rainwater is allowed to fester on top for 12+ hours until the pump kicks on, then that could be an issue also.
