What kind of salt can I use for my Volcano Shrimp (Opae Ula) shrimp tank ?

I use only aquarium sea salt for my volcano shrimp (opae ula) tank.

I mix them with my home made distilled water.

Do not use common cooking salt such as Himalayan Salt, French Sea Salt or Portuguese Sea Salt.

It will kill the volcano shrimp (opae ula) instantly !

Trust me, it happened to me.

Use only Aquarium Sea Salt. Do not use other types of common cooking salt !

I am using Red Sea Aquarium Salt, you can use other brands as well.

Make sure it indicate aquarium sea salt for marine tank.

a) Red Sea Coral Pro Salt Mix

b) Instant Ocean Reef Crystals Reef Salt

c) Brightwell Aquatics NeoMarine Marine Salt Blend

Can I make distilled water for my volcano shrimp (Opae Ula) tank ? It is more convenient and readily available whenever I need it.

Yes, you can. I have been doing it for years.

You need a steam water distiller. It can produce up to 4 litres of distilled water.

This is a 4 Litres steam water distiller

The machine boils the water until it turn into steam and goes into the pipes.

The contaminants in the water are left in the bottom of the tank.

Look how dirty it is !

A fan above cools the pipe and turns the steam into droplets of distilled water,. It is collected in the glass container.

The water distiller cuts off the power automatically in about 7 hours. The hot distilled water will cool down to the room temperature.

It takes about 7 hours to produce 4 litres of distilled water

Where can I get the above steam water distiller ?

What kind of water should I use in my volcano shrimp (Opae ula) tank ? Tap water, Rain water or distilled water ?

The best water for the volcano shrimp is aquarium sea salt mixed with pure distilled water. The reason is because there are chemicals and impurities in our tap water.

Chemicals are added into our drinking water to kill bacteria and pathogen.

The water is pumped come from our water company all the way to our house through various water pipes. These pipes introduce dissolved metal and impurities into the tap water.

Alternatively, you can always collect clean rain water. But before you do that, let it rain for about 15 mins or longer to wash away any surface contamination.

The rain water collected will be much cleaner.

Pure Bottled Distilled water for drinking

Where can I keep my Volcano Shrimp ? Is plastic or glass container better ?

You can keep your volcano shrimp (opae ula) in any plastic or glass container. 

Just do not use any metal container as it will rust and kill the shrimps.

Glass bottle tank with plastic lid

You can DIY and cut an acrylic sheet to be used a a tank lid.  

Volcano Shrimp Acrylic Tank

I prefer heavy, sturdy glass tank as it will not stain and you can scrub the tank easily without scratching it.

Remember to put a lid over the tank to prevent evaporation loss.

Water evaporate will cause a change in water salinity, thus kill the volcano shrimp (opae ula) slowly.
