Hi everyone. Over the past 3 days I have lost 6 acros. They literally STNd overnight. I tested for copper with my Hanna checker this morning on a hunch and got -
RODI - 0.0
Salt mix - .02
DT water .12
Last weekend I put about 1kg of formerly live dry rock from my LFS in the tank. Tank is 130 gallons with a ton of rock in there already so I didn't think much of adding a bit more.
I'm hesitant to blame the new rock because I've had the tank up for 18 months. I have occasionally lost SPS to STN and generally the tank has never really thrived. On the other hand, having 6 corals blow up in 3 days after adding new rock is suspicious.
This is what I've done this morning -
- Added carbon
- Removed the new rock
- Removed any equipment that isn't necessary in case there is rust somewhere.
- Checked my heaters
- Haven't changed any water because I was concerned my salt mix might be a problem.
Is there anything else people would recommend?
Is .02 copper in the salt mix acceptable or is there a problem here?
Can I reasonably expect to be able to remove the copper with carbon and water changes or do I need to start again with new rock?
