Salt amounts pls help ASAP

[finley]

I have RedSea Coral Pro Salt and am looking to make 10 litres of water, I have my 10 litre RO but how much of the salt do I add to it ?

You’ll need to mix in about 1.325 cups to get to a sg of 1.026

How many grams is that ?

I mix by the cup, so no idea

 

[Mr. Mojo Rising]

Don't you have a salinity tester?

~298.83 grams

~298.83 grams

️ thank you

Make sure you check the salinity before assuming it's correct.

lol

How do you know it is not 298.82 grams? The OP didn't even say what salinity he wanted.

He did

He did

Most of my comment was sarcasm related to the crazy number of significant figures in your post, but in reality, the OP still has not indicated what salinity he actually wants.

By the way, how did you come up with that number?

That’s going to be less than 30 ppt which seems a little low.

️ thank you

i would base it on 35 Grammes per litre, then test it with a calibrated refractomer, whatever. You may have to add a bit more if you want it to get to say 35 parts per thousand. You can convert grammes to egg cups or similar when you get an idea of how much salt it actually takes.

I forget, how many egg cups in a foot pound?

Ostrich or chicken?

Just expanding on GARFS comments, 298.82 grams of any salt mix in 10 liters of RO water produces a very low (unsuitably low) salinity, well below 30 ppt (below 1.0226).

Ostrich or chicken?

Um, not sure. :)

Um, not sure. :)

African or European?

African or European?

Um. If I have an egg in an egg cup, how do I know which it is?

Poke a hole in it and tip it upside down. The African ones run for ages, they are well known for it.

Perfect. I'll add that to the online calculators.
