I have a brackish tanks, so I know this really belongs in the fresh/brackish discussion, but I also know that you guys will be able to answer this question much better!
Instant Ocean says to use 1/2 cup (8 tbsp) per gallon of water for a marine environment. My question is, approx what SG
would that leave the water at?
I just need to know that so I can figure out the right amount of salt to be adding to my brackish tanks to leave it at around 1.010-1.013. I keep getting it there and then after a few water changes it's down to 1.008 or so. I just use a general scoop right now, and I'm trying to find out an exact amount that I should be using per gallon.
