Since we cleaned up our swamp about a month ago, we've had perfectly balanced, crystal clear water. I did a full test 3 days ago and all the numbers were in range. Daily pH and chlorine tests on Wednesday showed 7.5 and 6ppm. We woke up this morning to a completely opaque, milky white pool. All the numbers are still the same except chlorine which is down to 0. (CC 0.5)
What happened? I'm running out for chlorine now to shock the pool, but I would love to understand what caused this. As I understand, dead algae would make the pool milky, but I never had anything but clear water.
The other numbers are:
ph 7.2 (this had been hovering at 7.5 until this morning)
