I have several different ways to test, and am finding some wide differences between test methods for the same test..
ie.., API 5 in 1 test strips show PH at 6, No2 and No3 very high. Yet my glass tube style dropper bottle test it shows PH at 6.8, Nitrite at 0-5
Even two different bottles of PH solution give slightly different reads...
SO I guess, What I would really like is to find ONE consistent reliable master test kit...
Recommendations?...
