keep em out of your tank.

test for copper - they are VERY sensative to cooper.

yeah i think salifert has a Cooper test kit. Your LFS may test the water for you for a small price considering you dont really test for copper regularly.

did you buy your tank brand new or did you get it used? traces of copper could have leached into the silicone.

whats your salinity and PH?

Ur salinity should be around 1.024 or 1.025. This could be the issue but ur salinity is technically on the low side of acceptable limits.

Did u ever medicate ur tank when u had fresh water fish?

How are you checking your salinity?

If you are not using a refractometer, you should be. If you are using a refractometer, when is the last time you calibrated it?

I lost an urchin because my refractometer hadn't been calibrated recently and I thought my SG was 1.026. When I calibrated the refractometer, the SG was 1.023.
