Yeah, I was gonna keep pH at 7.2, but I just left it at 7.4. I added the 107 oz of baking soda, stirred it around, waited about an hour and added the 95 oz of liquid chlorine to get to 10ppm. Since CYA was somehow already at 20 I just put a chlorine tablet in the floatie. I checked FC and It got up to 10, I checked it 2 hours later and it was still at 10, that was last night, I just got up and was going to go check right now. So I don't need to worry about CH? The guy that came to my house said I didn't need to worry about it, but when the pool guy checked the water he said I needed to add some Hardness plus, he gave it to me for free though so if I don't need it I'm not gonna use it. What about the copper and phosphates, I didn't really read toi much about that in Pool School?
