How much SW does a pail of IO actually make??
 

It's been a long time since I mixed a whole bucket of Instant Ocean in one go. I seem to remember it mixes 180 gallons at 1.023, not 1.0264.

Could anyone confirm the number of gallons a pail makes at a certain SG?

I just made over 150 gallons this week of 1.025 salt for the new tank and I got a few cups left maybe 7-8 so it's pretty bang on it says 160 on the side

From the instructions on the side of the bucket;

"1.5 lbs of Instant Ocean is formulated to create 5 gallons of saltwater at a specific gravity of 1.022"

Front of bucket also has;

"160 U.S. Gallons, 605 Liter Mix, Net Wt. 48 lbs., 21.7 Kg"

Looks like Craig pretty much confirmed the numbers in his post.

I usually use 12 cups of Instant Ocean to mix up a batch of about 23 gallons of water at 1.025. Sorry that doesn't help with the full bucket routine! I've never measured how many cups I get out of a bucket.

From our experience it never makes enough salt like they say it does @ 1.026.

I add the exact amount it says on the bucket (0.5 cups/gallon) and always end up with 35 PPT water on the dot, so I assume the 160 gallon claim is accurate too.

Thanks for the replies! So, no one has ever mixed up a full bucket in one go? :lol:

I don't have container large enough to hold that much liquid! I imagine some folks with very large tanks have. Might need to post the question on a forum that has a 'large tank' category... hint hint.

& Craigd in post 2 came pretty close, I mean, what's a cup or 8 of salt when you've mixed 150 gallons.

I used the bags and I think 4 bags made 180 at 1.025, but 4 bags is a little more than a bucket.

I do all the time.

Our mixing containers are 250g each.

AquaVitro Salinity is the only salt that the claims are true. They say their salt bucket will make 225g @ 1.026 and its true but not many people use that salt brand.

I know that in the box containing 4 bags, designated as 200g worth, each bag only makes about 46 gallons at 1.026.
