Don't know much! Have ???'s :)

I don't have a sw tank and probably won't for a while.

For a standard FW tank a tsp per gallon is alright. How many teaspoon or table spoons per gallon would a normal SW tank have.

I know about the salt (marine) being different and almost everything else as well, lol.

This isn't about keeping a tank, just the salt quantity/ comparison.

For that matter, how does that compare to a basic brackish tank (teaspoons per gallon)

Anyone help me answer these nagging questions I always forget to find the answer to?

It would be a ton of teaspoons if you counted them for saltwater. I believe it takes me 2-2.5 cups of instant ocean to give me 5 gals at 1.025 salinity. It depends on the brand of salt as well. I did the math, and it would be about 24 teaspoons per gallon for 1.025 specific gravity

A brackish tank will have a very low salinity, I'm not sure about the teaspoons to gallons ratio, but many keep their brackish salinity at 1.01-1.015 I believe

Edit- according to liveaquaria, 1-2 teaspoons of marine salt for a brackish tank

google tells me that 2.5 cups is 120 tsp

120 tsp divided by 5 Gallons is 24 tsp per gallon!

WOW, that is considerably more salt.

Thank you!
