How to test accurately with the help of test kits?

[Weyou]

Hello to all forum members, my corals do not look good, so I bought test kits for a lot of money. Alklinity and phosphate I bought Hannah, calcium and magnesium, Salifert and nitrate and nitrite from Tropic Marin. I saw endless YouTube videos in English and read and did everything, but each video shows things differently and I'm not sure already how to test, this thing is very important to me to diagnose the problem in my aquarium, I can not perform tests accurately, each video has different tips but even One does not explain clearly enough for me, I have no knowledge of English at all and everything is so difficult for me

If you don't trust yourself on test kits yet, then I would use frequent water changes to keep the water parameters good until you get the hang of the tests.

We need a translator, either where you live or an app for us to use. Any ideas?

No matter what you use consistency on how you test will play a big part in the results.
For instance - when I use a powder I level the spoon with something instead of just eyeballing it.
Keep it the same all the time.
