Default Yikes...what's happening to my tank?

OK here it goes.... I noticed my kenya tree was dying so I tested the water and everything was OK except salinity.....it was WAY too high. So I began changing the water (Adding regular water) to get the salinity in check. Turned out a lot of the water was changed. Since then my cleaner shrimp and sally light foot crab have died. Now I noticed my sand is turning reddy brown and so is the live rock. My fish (yellow tang, perc, royal gramma), snails, hermit crabs, urchin, starfish all seem to be doing fine. Any ideas what is going on and what I should do? I am moving at the end of the month so I will be moving my tank as well. I'm hoping everything is OK.

I would guess that your fish died because you changed the salinity of the water too fast. Now you have added alot of fresh water of unknown quality and introduced algae or shocked the tank so badly that you have started a cyano bloom.

Yeah, what he said. I'm guessing the rapid change in salinity killed your inverts. As well, tap water contains things that could cause algae blooms (or cyanobacteria).

RO/DI is Reverse Osmosis/Deionization.....a form of filtration most reefers use to filter their water.

I highly doubt that tap water killed his fish...I have been using tap water for 9 months and my tank is thriving! When I do a water change, I mix the water and do the water change right away.....I know a lot of people mix the water for a day or even for a few days but I have never done that. So far my tank is looking pretty good. I think there are a lot of thing that happen and are very hard to explain why they happened. Most of the time we guess but we don't really know the real reason why something happened.
