Also, is it god to follow the 35gph per inch rule or is it more the better?
I think Santa is going to tell ya to measure it, under actual operation. In other words take a known gallon size bucket, and use your stopwatch (on your cell phone) to measure how fast the gallon bucket fills up.
I do not ever, and never will trust the numbers printed on the labels. I will measure mine and adjust accordingly. :geek:
