Harmful to Corals but Not to Fish?

I think we figured it out calcium was only at about 140 and the ph was super low thank you everyone for your suggestions they were extremely helpful

water changes

how often do you do water changes
that should have kept the calcium and ph up
you should not have to dose with no corals to use up the minerals water changes should have kept it up
good luck

Check your environment possibly. Pesticides, painting, fumes, etc getting into the tank can do a nasty number and you would be surprised at how far stuff like that can travel through a house or open window. I don't think it takes much to kill the sensitive stuff that is dying in your tank.

How high is your nitrate level ? How long your corals die after you put them in? How they die ? What are the types of coral you put in ?
