I'm testing with a hydrometer. So is there any benefit in raising it to 1.025? The reason I have mine at 1.023 is because I figure if I get something from the fish store thats has a SG of 1.021 ( which my LFS has) then it would be easier for the fish/coral to adjust. I just use 1.023 because its kind of in the middle of the range. Make sense?
