RYE PA Brew Session

I started brewing after 1pm and finished up right at 7 with cleaning and everything. added corn sugar last 15 minutes of the boil. I had 1#2oz so I just added it all Sparging only took 30 minutes. I'll see how it affected FG and make an adjustment My calculations were better this time with mashing and sparging. I got exactly 7.5 gallons in my boil. I'm a little worried about my yeast handling. I reconstituted the yeast but i didn't sanitize any of the stuff or boil the water. Oliver T's only had 1 packet of my yeast but i needed two. Next time just dump the yeast on the wort. I let the flame out hops sit for 15 minutes then I started the wort chiller but didn't agitate it until another 15 minutes had passed. My oxygen tank ran out after about 14 seconds Fermentation started about 3pm the next day. I started fermentation in the basement where the ambient temp was 68 the day i brewed it. I moved it upstairs at 12pm the next day because I saw no action in the airlock. OG was down 7 GU's. i had a shorter sparge so maybe my efficient. or my mash PH was high and that affected it. I still need to work on my water chemistry. 6/18 I checked the gravity bc the airlock stopped. It still had good krausen and the gravity was at 1.012. I'm hopeful that it gets to 1.008 or so.
