You should aim to keep potassium levels around 380 to 400ppm
Maintaining Potassium at natural sea water levels can lead to brighter colours in small polyped stony corals.
10ml will raise Potassium levels by approximately 10ppm in 100 litres of salt water
It is not recommended to increase Potassium levels by more than 10ppm per day.
Simply mix the required amount into a few litres of Reverse Osmosis Water, once dissolved, slowly add to your tank in an area of high flow, preferably over a period of an hour. Alternatively add to your evaporation top up water and top up as normal
