The Opae ula shrimp Forum and online store

Hello.. I am very new to shrimp. I am from Singapore

May I know what type of water to mix with salt for starting the tank ? Distilled water or RO water ? or tap water with decholrinator ?

I read that distilled water is too pure and contain no minerals so maybe not as recommended ?

Please help me.. thanks

Sorry.. I don't see any option to delete or edit post. I just read that RO water is best for setting up tank!

Reverse and distilled is fine as the marine salt use to crate the brackish water contain all the required mineral and stuff.

Can I wash the substrate in tap water before putting into tank?

And final wash in distilled water ? Or everything have to be done in distilled water ?

Yup as said above. RO or Distilled is what to use. :)

if you wash them in tap water, it is better to dose some anti chlorine.

Hi. I have just set up my tank today with RO water etc and added marine salt (175g to 10.1 litre).

Now I want to start the nitrogen cycle. I read a few blogs and they suggest that I dropped some shrimp / fish food to kick start ammonium. Is that wise?

I was planning to buy some pure spirulina powder as future shrimp food anyway, can I just use that? How much should I dose the water for 10 litre water?

Many thanks!

Welcome! @Chaiwatuk I would just let the water sit for a good month and test the parameters for ammonia, nitrite and nitrate.

Many thanks @odin

Yeah, generally if you leave the tank filled, under light, when the algae starts growing it's ready for Opae Ula. If you are putting a lot of them in a small tank then I would worry a bit more about cycling the tank with food before hand.
