Thanks StirCrazy

is it 150 gal of actual water in there? you have to figure out how much you rock displaces ect.. also I don't know anyone who fills tanks to the top. a easy way to confirm it is to mix 3 cups in a minimum amount of ro water (enuf for it to desolve) then add it to the sump then after 24 hours check your salinity and see how much it changed and you can go from there.
