If I compare salt mixes made by different manufacturers
and I take one pound of each to the equal amount of water,
would I get the same brine density?
In other words - are there any differences in how much
the salt mix weights?

I believe there are differences. A shop owner recently showed me the
200gallon mix of Tropic Marine Salt compared to the 200gallon mix of Instant
Ocean. The bucket of Tropic was a good deal smaller. He claimed IO uses
more fillers, so less is needed with the Tropic Marine. It appears that it
weights almost 10lbs less as well. So, at least comparing these two brands,
it would appear that one pound of each to the equal amount of water would
yield a different density.

Years ago i used a salt mix called Forty Fathoms, not sure if its the same
as the current Crystal Sea Forty Fathoms or not, but it came in a 8" x 8" x
12" box and that was enough for 150 gallon. best i remembere it was a cup
of salt to the 25 gallon.
just threw a box away about 2 months ago that had to be at least 20 yrs old,
didnt see a need to keep it, damn sure wasnt going to try and use it. even
tho i had great luck with it in the days.

Tropic Marin is way under weight, my experience mixing a 50 gal box at 1.024
yeilds about 42 gal.

IO is the same way for me.
i added a 200g mix bucket to my 180 and it came out at 1.019.
i keep my tanks at 1.026 and with the 100g sump/fuge on the 180 i had to
add most of another 200g bucket to get the salinity up.

How acurate is your tank volume estimation?
Have you account for walls/bottom to expand, silicon stretch under
the water pressure and actually increase the capacity of the tank?
I am curious how did you do your calculations. What error margin? 10%? 15%?
It is interesting subject... Could you guys read "net weight"
of the salt from your bags, buckets for the comparison?
BTW - when the manufacturer states "the amount of salt is for
200 gallons" - what salnity/SG do they have in mind? :-)

I often have to make small batches of artificial sea water. I do it by
weight. Instant Ocean is pretty close to 35 gram yielding 35 ppt on the
hydrometer. Chrystal sea needs about 41 grams for the same salinity.
Always check your hydrometer against a good one.

with stand pipes installed and filled till it starts to overflow to the sump
it took 165 gallon. the sump holds 125 gallon but is only ran at the 100g
mark for a margin of error when power outages occure. but when i filled the
tank i added 200 gallon of ro/di water and then added the entire bucket of
salt and let the system circulate to mix it. (no rocks or sand in yet) that
is when i got the 1.019 so it would not matter the exacts of the tanks
volume, the tank and sump had exactly 200 gallon and for your margin of
error id give it a +/- of 2 gallon or 1% because a few drops did splash out
here and there as i filled it and a tiny bit could have evaporated.
as for net weight the bucket is 64 lbs and that includes the weight of the
bucket and lid.

Hi,
What is the source of this info? Does it apply to all manufacturers?
Is this some kind of standard?

It's an old standard. The thought used to be that fish would do better in 1.021
instead of natural sea water strenth. And fish deaths used to be blamed on the
senthetic sea salts, because people back years ago didn't know anything about
amonia, nitirite, and nitrate, or how to test for it. If fish dyed they just
blamed it on the salt.
Now salt manufacturers still tend to use the old standard of 1.021.
Think about it, if you were a manufacure of sea salt, and you wanted to move to
a more normal standard, your salt would look like it cost more, because your 50
gallon bag would go up in price, even though it still cost the same per ounce.
And I think that's probably the major reason that salt manufactures have been
so slow to get up to date and accurate on the specific gravity.
