Don't forget a little PH down just in case it goes up too much and you need to bring it back down. It took me a little while to get the hang of it and I over did it a few times. I was in a hurry and messed up. So a little at a time till you know how much it will come up for your rez size. I guess I'm one of the last ones who learned a great deal from Zandor. He was always here and a great help to many. Glad I could make sense of it.
