how much ounce or gram in an IO cup ?
 

So, I got an used and half full bucket of IO salt and it didn't come with the cup. Can anyone please tell me how much grams/ounce one cup holds ?

I will need to start a 65g, so have to mix the water tonight.

Thanks in advance,
Raj

Instant ocean buckets of salt do not come with a cup. To my knowledge no salt brand comes with a cup. Just use a measuring cup from your kitchen.

Measuring cups come in different sizes (if I am not mistaken), so which one do I use ?

you will need 32 1/2 cups.

The number of grams varies in a cup due to particle size, for salt its around 292g per cup. 1 Cup also equals 8 ounces, I'm kind of confused what your asking though.

1/2 cup salt per gallon of water

What I am asking is that if I just have a bucket of salt, how much will I need to make a gallon of water of standard SG. IO says 1/2 cup, but that is irrelevant to me as I don't know how big of a cup to use. Hence I am asking for the metric amount that a cup holds. If I know the gms or ounce, then I can measure it out.

Look on the pail, says pail makes 160g (605l) and weighs 48lb (21.7kg) can figure it out with a little math but a cup traditionally is 8oz (volume) or 250ml.

I will go ahead with a measuring cup and measure out 8oz for 2gallons of water. If the SG is fine, then I am good.

Thanks everyone.

2.5 cups will make 5gal of salt water. Use a 8oz cup as Mark stated

I never measure, just throw it in and top it up until I hit 1.025 on the refractometer.

I do mine by weight 1.5 pounds of IO to 5 gallons water. you will need 19.5 pounds of IO salt.

Thanks to everyone for their help. Finally I can get my tank up and running.

I took a container that was about the right size for the volume of water I wanted and threw that salt filled up to the top into the bin. Then filled it with water until I hit the right salinity. Put a mark on the bin and now I just fill the bin with water to the line and throw the salt in from the container and it is the same always.
makes changing the water a bit smoother.

You use a Measuring Cup. 1 cup is a standard unit of measure. they make measuring cups in 1/4,1/3, 1/2, 1 cup measurements.

That was a painful thread to read

Tell me about it!! I'm a Chef by trade and I think a little bit of my brain exploded reading that. My wife is wondering why I'm yelling at the computer "A Cup Is A Cup!!!"

No, a proof is a proof. What kind of a proof? It's a proof. A proof is a proof, and when you have a good proof, it's because it's proven

Ok it's good to know I'm not the only one who temporarily thought about gouging out my eyes with an algae scraper after reading that.

I did not read the whole thing I just gave my answer 1.5 pounds makes 5g water.

lol

Wow what a thread about a measuring salt. what is this world coming too. add salt and test it later. too much salt add WATER, too little Salt add more SALT..............
