Wash and clean the item with clean water. Do not use any disk washing detergent or soap.
This is to prevent any leftover chemicals from killing the volcano shrimp (opae ula).
Pour the bag of volcano shrimp into a clear container. I prefer clear container as I can put a piece of colour paper underneath. This way I can easily differentiate the shrimps.
Remove as much water from the container as possible. We are going to prepare and add in new water a little at a time. This process is called drip acclimation.
Open a bottle of distilled water and pour it into the measuring jar. I do not recommend tap water or mineral water due to chemicals in the water.
Pour 1 Litre or 1000ml of distilled water into the measuring jar.
Take a spoonful of aquarium sea salt . Any brand of aquarium sea salt is fine.
Here I am using Red Sea salt.
For those of you who do not own a salinity refractometer or hydrometer, you can use a weighing scale to measure the amount of aquarium sea salt.
Weigh 15 gram of sea salt exactly.
Pour the salt into the measuring jar.
Mix 1 Litre of distilled water with 15 gram of sea salt.
It will give you 15 ppt (parts per thousand) of salinity.
It is also equivalent to a (specific gravity ) S.G. of 1.0113.
To get the correct salinity of the salt water solution, all the salt must be completely dissolved.
Stir thoroughly to dissolve the aquarium sea salt.
