Add a 50 gal mix and two more cups OR
in simple terms. . . . 1/2 cup per 1 gallon

Salt BrandMixing Recommendation
Instant Ocean1/2 Cup per 1 U.S. Gallon
Red Sea Salt136g per 1 U.S. Gallon
Tropic Marin Classic Salt1/2 Cup per 1 U.S. Gallon
Neomarine Salt Mix134g per 1 U.S. Gallon

Most mixes use about half a cup per gallon of RODI. Add a bit less, Mix it (a powerhead in the tub really helps). When it is clear, check the salinity and add until you get the salinity that pretty near matches your display tank.

I weight my salt for better accuracy. I use reef crystals and for 53 gallons I use 17.5 lbs. of salt . Salt reading 35.00 / 1.026
Yep. Weigh it as per the instructions for Aquaforrest. 390gms per 10 liters or for lesser amounts 39gms per liter.
Then adjust adding more salt or RODI water as required. 33% salinity or 1.025 SG

To weigh
place measuring cup on scale and hit zero/tare to negate weight of container. Then add salt to get only weight of salt.

I agree with above:
Estimate about 1/2 cup of salt per gallon of fresh water, mix, and verify salinity.
Add water or salt as necessary to adjust and write down estimation with correction factor for future reference.

For me, I typically mix my saltwater right now in a 44-gallon Brute can. I use Instant Ocean salt, though I have also used Red Sea black-bucket in the past with similar estimation measurements. I typically fill the can near the top, estimate 40 gallons, and add 24 cups of salt to get a salinity at 1.025-1.026 specific gravity. Note that I am correcting slightly over the 1/2-cup added per gallon estimation.

Hope this helps!

Just reiterating that it is mix dependent because the moisture level varies by mix.

Some, like Brightwell neomarine, take less mass to reach the same salinity (not necessarily a benefit, just a fact).

use manufacture recomendations and then a refractometer and calibration solution to get it to the exact right level
