so noticed tips alk burn on sps.. but how can that be. Trident shows 7.8. Tested with Hanna and I am at 9.4 ... My tank does better at lower dkh. I have held it for years at around 7.5 to 8. I calibrated the trident twice now and still getting readings of 8.3 or so and the Hanna is at 9.4. I then checked with some other tests and then show 9.5 or even higher.. none showed below 8. Thoughts..
1. bad batch of reagent for the trident ?
2. Trident is right others wrong
3?
