Problems Reading API pH Test
Okay anyone who is familiar with this test may be able to help me out, no matter what time of day or night I test my water with the high range solution the tube turns bright orange - not light brown, not bronze - orange. That says 7.8 on the high range.
The regular range solution is the only one that changes from about 6.8/7.0 to 7.6 (blue).
- Why does the high range never read 7.4 (bronze) if my normal range reads 7.0?
- Should I just use the normal rage pH solution?
- If the range is dark green-blue I am good as long as the high range is orange?
