My chemistry was:
FC 15 (on it's way back down after shocking after a pool party)
Water temp ~90-92
I like to keep the pH around 7.4 and usually use borax to raise pH, but was out of it, so I used pH+ (sodium carbonate) to raise the pH. When I put it in, it instantly clouded the water as it dispersed- a milky white cloudiness. It stayed cloudy all evening and by the next day it had cleared up. Did adding the sodium carbonate cause calcium to precipitate? I added a small amount of ionic clarifier just in case and by the next day it was clear. I have no idea if the filter cleared it or if it was a precipitate that reabsorbed? Any ideas? Not sure if I should use that again (even in a pinch).
