Each brand of marine salt has its own particular mixing instructions which you should follow. In any event, get a hydrometer (or better a refractometer) and make sure you end up with an SG of 1.024 to 1.026.

the salt brand is instant ocean . is 25 cups right for 50 gallons this is my first salt water tank

[O.C.D Fishies]

1/2 cup per Gallon. I used this but still had to tweak the end results a bit. So yah 25 for 50 should work.

[fkshiu]

1/2 cup per US gallon according to the side of one of my empty IO buckets so 25 cups for 50 gallons is correct. Regardless, always check SG carefully after thorough mixing. With a hydrometer this means tapping out ALL the air bubbles and ensure you are measuring heated (~78F) SW because SG varies with temperature.

Johnny very good idea to invest in a refractometer when you can, way more accurate and easier to use, all you need is a couple drops of water.

I think IPU has them for $40.
