Dude!!! Where in the world is your e-brake? If you were a race car you would be leading the pack but what you do not relieze is that you are about to loose a tire. You had some big problems just a bit ago and now you are adding fish? I checked the refractometers for wine and found out that saltwater throws them off, compared one to a refractometer for salt water. Anyway like Al said make changes SLOWLY this is VERY VERY IMPORTANT. Sudden changes will stress and harm fish and corals. I also found that beginers reading ,even though I had already read it, really helped to reread it.
