well, my sal is 1.026 and it stays solidly there (tropic marin reef pro). I'll try to list my other params, but I'm not sure I remember how to read my api tests. LOL. Probably not what the GB folks want to hear. . . I am pushing a little iodide right now so they had good healing waters, but I dose so little it's probably a placebo for me. Right now I am getting explosive growth in all of my corals. I attribute it to not having a lot of time to look at my tanks and having it jammed in the corner of a construction site so that no guests can see it without a hardhat.
