Well, let's not get ahead of ourselves lol.
So I took in a water sample to the LFS
today, and they use seachem. Calcium was confirmed at 300, which is in line with what my api kit shows. Alkalinity, however, was 1 meq/l, or 2.8 dkh
. That is way off from the 7 dkh
or 2.5 meq/l my api test shows. I mean, we are talking 60% lower, or better yet, the api kit is showing a result that is 150% higher than the actual level!
So I am in the market for a new alkalinity test kit, what do you guys use?According to this article: Product Review: Alkalinity Test Kit Showdown â€” Advanced Aquarist | Aquarist Magazine and Blog
Salifert and seachem yielded results that were within 10-11% of the actual alkalinity level, which the author considers acceptable. Red sea was approx 19% low, but the author admitted that it is subjective as it is very difficult to distinguish the color value. The other kit is Tetra, which the author said was 32% higher than the actual level and thinks the regents were a faulty batch. This article is almost 10 years old, so all of this could be different now, but what I do know is at the fish store today, it took him about 30 seconds to do the seachem KH
test, so I am leaning in that direction. I know of the hanna checkers, but everyone seems to prefer the phosphate checker and I have not heard much about the others like KH
