"Our Lord! Give us in this world that which is good and in the Hereafter that which is good, and save us from the torment of the Fire!." -(Surah Al-Baqarah, verse 201)
Saltwater Aquarium 101 - Water Level
Having an indoor aquarium, it needs to have a screen top to avoid the fish from accidentally jumping out. Since we use glass as a screen top, we can only close it partially in order to allow sufficient oxygen dissolved in the aquarium.
The cons?
The water level in the aquarium will bound to be reduced due to evaporation after a few days.
What can you do?
Set a minimum mark at your aquarium, so that whenever the water level reaches that point, it indicates that water needs to be added.
How to prepare the water?
Use reverse osmosis (RO) or filtered water, add in coral reef pro salt, and circulate the water for around 3 hours using a submersible pump before measuring it using a Seawater Hydrometer to reach 1.024 specific gravity (recommended coral reef tank is between 1.023-1.028, depending on individual preferences). Add more salt if they are too low and more water if they are too high.
Salinity is typically measured in parts per thousand (ppt) or specific gravity (sg). Specific gravity indicates density, expressed as the ratio of the density of seawater relative to the density of the same volume of pure water.
How much salt to add you ask?
Well, we usually use this ratio, for every 10 liter of RO water used, add in 250ml salt to achieve 1.024 specific gravity. You can also refer to the manufacturer's instruction. I have no idea why they use ml unit instead of gram for measuring salt, but yeah, a measuring a cup is provided as well.
