I have liquid and strips that I use, sometimes using both just to compare readings. In the case of my pH, my strips say it is at 6.4, whereas my liquid test says it’s closer to 7.8. How can they be that different? I would take it to my pet store, but they use the same strips that I do.
My other concern is that last night, with the exception of my pH, everything was at zero. Ammonia, nitrate and nitrite. They had all been a little above zero, but that’s expected since I had recently introduced a betta. Now they show they are all at zero, even the nitrate. I think I did something wrong in testing. Is it a good thing or a bad thing when they all drop to zero? Would it be safe to introduce another batch of fish, or should I wait a couple more days and continue to test the water?
