Question Alk test

Hello, Im a new and I have a question about the alk (KH) test (Landebao chinese test). On the manual, its writed to add 5 drops until the sample's colour turn into yellow.

Okay but when I add many drops only the top of the sample water turn into yellow and the bottom keep transparent.

So I should follow only when it become yellow at the top or when all the water turn into yellow ?

Not familiar with that test but I would guess you should gently swirl (not shake) the sample, then compare.

Sorry my mistake, its not 5 drops, but add drops as many as needed, each drop equal to one degree of hardness.

Okay I will try to shake after each drop and see.

Okay, that's it, I have to gently swirl after each drop until colour turn into yellow, it was not writed on their manual...

So my alk is 7, is that okay for a newly started tank (17 days so far).

need to keep alk stable applies once you start stocking it with corals, especially sps. are you still cycling your tank? if so dont worry about alk level yet.

7 dKH is fine. I wouldn't want the level to drop much lower in a tank with corals, but for a new tank, I wouldn't worry. This article might help:
