ph test

I don’t currently monitor pH. How important is it to monitor pH? I use GFO which I’ve heard can affect it. Looking to hear thoughts on what you do and if you think there’s any value to monitoring or testing it

So I tested my water with a Red Sea pH kit, and when I look at it from above it looks like a watered down purple but when I look at it from the side it looks blueish/grey. What does that mean? lol... I can't take a pic because with the camera it looks purple no matter what.
