Measure your water with other tests, and use the one that matches the results in the Ari test at the specified milliliters going forward.

I ask the moderators to move the topic to the Ari section. Thank you!

5 ml is naturally taken as "normal." Test tubes can be "non-fountain" (SERA ones, in general, do not match at all). However, I haven't noticed this with API (I used both for calcium and the basic set - excellent droppers and very convenient test tubes with a stand). By the way, pay attention to the first reagent for calcium - you need to add 10 drops (in many other tests, it's 5).

Old man Mokho, regarding the 10 drops, I figured it out, thank you... And the most interesting thing is that I have tests that are made specifically for the American market, not specially for our countries... For such nonsense, Ari could really "get hit" for several million if someone "fails" their rhyme based on her tests.

I once checked their test on the standards. As far as I remember, it turned out that you need to pour according to the markings on the test tube.

Mr. Hatak is absolutely right. Fill to the mark, and you will get a plausible result. I have been using API tests for about 11-12 years now. There have been no "failures." By the way, the reverence towards Ptero - the quality is top-notch for the money. Give it a try, you won't regret it. The main thing is to literally follow the instructions.

Offtopic Hmm, I always thought it was Mr. Natak)))) Okay, next time I'll fill it to the mark at the lower meniscus (but now the question is - at the lower edge of the line or the upper??? The line is wide, almost a millimeter...). I also use Ptero, and the only thing I don't like about them is the syringes - they seem too cheap and "Chinese." Yes, the piston doesn't reach the end, and it constantly sucks in an air bubble with water, no matter how hard you try. That's why I use a 5 cc syringe from the pharmacy for drawing water. I hope this doesn't affect the measurement quality...

I think the mark will be within an acceptable margin of error. Off-topic)))) syringes)))))) the replacement will not affect it.))))

Syringes can be replaced with Dutch ones with a rubber piston, or with graduated pipettes for draining, like on a burette. It's convenient. I collect and distribute from 2 to 5 samples at a time. The price is 2-6. I pour so that the mark on the apish test tube matches the lower meniscus of the liquid, although at such a volume, it's a negligible range. (By the way, I don't like apish test tubes. The stopper leaks in almost all of them). I am too, but during the phone conversation, he corrected me.
