Sorry about the audio quality in the video today. My microphone got disconnected somehow and I didn't realize till I was done recording.

Hi. Just wanted to ask, when to use Ph and when to use Ph high grain. Or exactly when to use one or the other. Thanks!!

Great question... Unless you know the general range of your water, it's hard to know when to use the high vs low range pH tests and the whole point of the test is to figure out what range your in! You can either ask your local fish store what your local water pH is, or you can get a digit pH meter, which is what I use. Link for it -> amzn.to/3yvDM3b
