So I tested my PH the other day and wasn't sure to use high range or low range. So I did both. The low range came back with about 6.0, and the high range said it was 8.8+. I don't know which to believe. I could not find any information from my water supply company other that "PH ranges from 6 to 8".. thanks.. Which test should I believe? I'm going to do them both again now and see if I get different numbers since I just did a water change yesterday.

Test again, that range it pretty huge. What is you tap water range? This time of year, depending where you live, things can be...different. Can you give us a state or area where you live?

I'm in Woodinville Washington. I'll test again tomorrow when I'm home. It is such a big range, and both tests showed the edge of their scales last time which is why I'm so confused

I would suspect an error in testing first. Also, compare your tank readings to a tap sample that has sat out overnight to gas off.

I did the test again. I must have done it wrong the first time. Its testing at a constant 6.4 out the tap and in the tanks. All is well! Going to increase it with ph up

I was just going to up it with one dose for the bettas and goldfish not continuously. I have 5 tanks with bettas, fancy goldfish, guppies, danios, neon and black skirt tetras, paradise fish, plattys and white could minnows. All well established tanks, between 1-6 years old, but as seasons change my citys water source fluctuates between rivers and what not so ph varies by a bit.
