soft coral and clownfish help!!!

[jwoyshnar]

Hello all. A few days ago i did a water change. It was nothing big. 5 gallons in a 55 gallon tank. The next day my corals were shriveled up and my maroon clown was gasping. All tests came back perfect except for the calcium. It was at 600-650??? It was at 400 before the change. i did change brands of salt from instant ocean to Kent as they didnt have any more instant ocean in stock when i needed it. Could this have caused my problems?
Thanks

It's highly unlikely (actually, probably impossible) for less than a 10% water change to elevate your Ca from 400 to 600-650. You might want to check your test kit.

Your SG is a little low, s/b more like .026.

Is it possible that some contaminant got introduced into your tank and caused the reaction you're seeing?

Agreed, highly unlikely the Ca is to blame. Are you running carbon if you are seeing stress?

Hello all and thanks for the reply. Im thinking it was my water. I used my well water amd i think that did me in. I did another chamge with RO water and things are improving.

Always use RO water or you will be fighting other issues, as well
