35 parts per THOUSAND
1.024-26 SG

That will help. I personally just do it myself by finding the volume in cubic inches and converting it to gallons by multiplying it by .004396...but I've tried out the calculator and it works nicely.

Wait, I thought 'ppt' stood for 'parts per thousand'...
I believe the salt to water ratio, when mixing water, is 2 cups of salt per 5 gallons of water.

There is no exact formula for mixing salt to water that I know of. Each salt mix is different. That's why have a refractometer is important. If you blindly add salt cups to gallons of water your asking for problems. Test the water about 20 minutes after you add salt and add more water or salt as needed.

I have a refractometer, but I was hoping for a general idea so I can get close to the amount without checking and rechecking

Yes, yes, yes. I slipped. Generally ppt represents 'parts per trillion' but in the case of aquariums, it does mean parts per thousand. It is also an abbreviation for "precipitate." So it's a real crap shoot. Thanks for catching that.

Most refractometers are ATC which means "automatic temperature compensating" (don't take my word for that, I'm having an off day when it comes to these things). Therefore, with a refractometer, you don't have to worry about temperature. With a hydrometer, the temperature will affect the specific gravity. Here is a chart. http://www.algone.com/index.php?opti...rium&Itemid=60
Remember that consistency is far more important than having that perfect number.
If you have a reef tank (or intentions on having one), then 35 ppt is what you should shoot for. If not, having a lower salinity will reduce the amount of diseases that can thrive in the aquarium. Around 30-31 ppt would actually be okay. Remember that this is my opinion and not anything that should be taken as a rule to fishkeeping.

Slightly lower salinity doesn't reduce the amount of diseases (at least to a worthwhile amount), but it will lower the osmotic pressure on the fish, making their job to breath easier which results in happier fish...

usually i do about 1/2 cup of salt per gallon of water

osmoregulation has little to nothing to do with breathing.
osmoregulation is about balancing the bodies fluid content, keeping it from becoming to dilute (oversaturated with fluid) or too concentrated (dehydrated if you will), in marine fish it is easier to regulate the bodies fluid content at lower salinities because there is less "material to exlude" when transfering water into the organism.
A marine fish has an internal osmotic concentration lower than that of the surrounding seawater, so it tends to lose water and gain salt. so they drink salt water and urinate concentrated salt urine.
its all about ionic balance of their bodies, since they maintain a level different from seawater the more extreme the difference is (higher the salinity) the more effort is required to regulate their bodies ionic balance. in a sick fish the extra effort to regulate can cost them energy that they could be using to fight off a disease. thus they may succumb more readily to a disease at a higher salinity.
