I am very new to this, and grateful there are those more experienced ones willing to help.
We had a lot of wind yesterday. I was washing out cartridge filters hoping to make them last just a little longer. but the "dirt" i them was greyish green. that tells me that I have an algae problem starting, correct?
Last night's readings: FC 4.5, CC 1, Ph 7.4, and CYA off the chart...guessing it's at 120. I know i will need to replace some water at the end of the summer...probably a lot of water; but what would my FC reading need to be to SLAM the pool now?
