Potassium should be kept at 400ppm.

Hi bro,

Just a precaution, when dosing such elements, it is better to get the corresponding test kit and make sure that it is not overdosed. Some trade elements can be lethal if overdose such as iodine/iodate causing the corals to bleach and die.

Potassium level testing is a bit more leceh (cumbersome) using Salifert (compared to the standard KH, Ca, Mg testing). Last time I did dosing for a short while but finding it too cumbersome and now only rely on regular water changes.

So, may be best just with regular water changes using good salt (just my opinion).

Coloration is actually a bit complex, bro.

One aspect is the coral pigmentation affected by water parameters and lighting.

Another aspect is the manipulation. The coral may have certain pigment but it can only be brought by certain light wave length. For instance many Corals looks nice under royal blue LED lighting. The nice luminicent color is not visible under normal light. Therefore, color can be manipulated.

This article is interesting on color pigmentation and the color excitation:

For practicality without the need to know all the nitty gritty, we can just refer to the TOTQ winners (refer to the TOTQ thread in this forum) to see how they maintain their water and what light they use to have nice coloration

For potassium level, some brand contains higher level. Assuming the manufacturer keeps the level consistent all the time, this reference can be used:
