Hi Guys,
I understand that hobby grade test kits are used more for reference and stability. I also understand that number chasing isn't always the best to do with our reef tanks. But I would like to share a story (photos included) and get your input.
For years my hanna alk checker has been the bible. I would trust it over my apex trident. Within the last month, I noticed my checker started giving very high readings, so I decided it was for $50 to replace it. Upon arrival of the new checker, I got very high alk readings complimenting the older checker's readings. After trying multiple cuvette, syringes, etc I was able to narrow down that the two reagents, purchased 2 months apart, were about 2dkh different from each other. I was able to replicate the attached results multiple times indicating it was in-fact the reagents.
I understand there should be so tolerance in these test kits, but 2dkh seems to be a lot. What are your thoughts?
