I want to close my pool so I decided to SLAM it instead of covering the "green pool". It took me about a 5 days to rid the pool of algae, but the pool is cloudy and my PH reading is weird. when I test it the PH reads 7.5, but if I let it sit for a couple of minutes, it goes up to about 8. Could it be that the water temperature is cold and then warms up to room temperature? Also the TA test doesn't change to red, it changes to yellowish color. I'm kind of confused here. should I wait until my FC levels start dropping before I try to check & balance both the PH & TA or is it safe to close the pool as is.
