Instant Ocean Reef Crystals crashed my Tank!

[Tiansho]

I am using RODI water and have been since I started my tank. I ran out of my salinity salt. I tried using reef crystals, and mixed my salt with RODI water, left mixing for two days. Reached salinity level 1.025 (same as my tank) and same temperature. Tank was doing really well prior to water change. And after...... the tank crashed. I got some salinity salt fron my brother in law and within a few hrs i saved what corals i could.

Any possibility that something may of fallen in the saltwater mix during those 2 days? You got kids? cleaning lady ? smelly aerosols automatically perfuming the room? that stuff can kill a tank

Even if it had been a bad batch, all the forums would be getting complaints by all the people who would have purchased the bad batch. I very much doubt that you would have been the only one getting a bad batch.
Salt mixes are often used as a scapegoat for things that go wrong, when it fact, at worst, it is only a coincidental occurrence.

It might have been that you switched salts.
The parameters for Reef Crystals may be different from the parameters of the salinity salt even if you have the salinity at 1.025.

I've read somewhere before that changing salt may not always be a good idea.
