I have heard a lot about pH crashes but haven't paid much attention to it until I did a water test of my indoor QT tank yesterday and my pH reading was 5.6! I thought it was the digital pH meter but the pH was still around 5.6 after I calibrated it. I immediately changed about 1/3 of the water in the tank and added baking soda until pH rose to 7.3. I heard that using too much baking soda is not good for skin/color quality. My question is, what is the best way to maintain pH at around 7.2-7.4 without using baking soda? I definitely don't want to be scared like that again!
