Checking the pH of your water in compared to the pH of your water out (or 'Runoff' pH) is one of the first ports of call when you suspect a problem, tbh i'm often guilty of not bothering and going by visual signs, but i'll still always want to check my feeds pH with my own tools before it goes in, and as noted before, i'm not going to want it at the EXACT same pH all the time, i'm going to want it to drift from it's normal 5.8 to within a range of 5.6-6.0 every so often.
