We have feedback that CityLink have poor service in Penang and therefore for Penang orders we will automatically use PosLaju while the rest of Malaysia will be using CityLink. Do take note that Poslaju might take longer to arrive as Poslaju last pick up ends earlier.
Use the Salifert Magnesium Profi-Test Kit to accurately measure magnesium in your aquarium.
Magnesium is a vital element in any aquarium as it is used by corals and coralline algae to build strong skeletal formations and healthy development. It's also an element of chlorophyll which is necessary for vital photosynthesis to occur.
Salifert Test Kits are very sensitive and will provide the most accurate reading possible. The magnesium reading is not affected by strontium or calcium levels, so you can be confident of the most precise readings
