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.

Some inverts like shrimp are sensitive to both quick temp & salinity changes so that is likely what did them in. As far as the algae goes it could be a number of things. How old is the tank? and how big? What do you have for filtration, etc? I would need to know some of this info before taking a stab at the cause.

how did the salinity get so high? What are you using to measure it? A hydrometer or a refractometer?
