I've been using the Aquarium co-op test strips and they are so easy to use that I've been getting low on them and decided to try the API Master test kit, it was on sale. I used the API kit and the only test that gave me pause was the Ph results, the Co-op test strips said I had 6.4-6.8 Ph But the master test kit says I have a Ph of 7.6 there was no green in that blue vial, so really concerned. I had a digital Ph tester that I have only used a couple of times it's a pain to use but it gave a Ph reading of 7.04... which one do I trust?
