This is the 4th day of SLAM.
From yesterday night to today, no change in water color. still green. CYA is almost 30. FC barely changed 12.5 to 12. CC is unchanged 0.5. Plus there are some milky stuff on the surface of the water, please see the picture I attached.
Can you please let me know what I am missing here and what is this milky stuff?
thank you.
