Can't figure out API pH test results, newbie
Hi there, question about ph test results. I have the API freshwater master test kit. I have a 38 gallon cycled tank. When I test with the regular pH, color results match the highest pH of 7.6. But when I test with the High Range pH, color results match with lowest pH of 7.4. Water straight from my tap is 8.4. Should I just assume the tank water is in the 7.4-7.6 range?
The tank is newly planted, has two pieces of driftwood and many rocks and a few shells I collected from the beach. Substrate is floramax, eco-complete and river pebbles, no CO2 or ferts yet. How accurate are the pH tests? Also, I don't use pH down.
