So per advice from James, changed the settings to t-9 cell to make it last longer. It worked great while we were out of town for the weekend!
The last four days have been rainy and overcast, and it seems I had my swg set too high for that weather so adjusted it down a bit so it's not uping the FC so much.
A little confused as to what is going on with my cya. It was 50 so I added 3.5lbs before we left last weekend. Testing today it was still 50.. I don't think rain would get rid of everything I added. Thought I was going to be all set there.
pH is going up, thinking all the aeration from rain probably didn't help. Will have to lookout for it going too high.
