Mr. Hans-Werner:
I am a relative newbie to reef tanks. However, I switched to your product after starting my tank with Red Sea Coral Pro. To me, this was a good salt, and when my LFS ran out, they sold me your product as a substitute. It is, as far as I know, a good product as well. Since switching over last fall, I've had huge issues with my SPS corals and frags that I had in the tank. Monti's grey out and die, and acros turn brown and mushy at the tip and then die as well. LPS corals have had polyp bailout. You can see my most recent post here at
http://www.reefcentral.com/forums/showthread.php?t=1998773.
I don't want to cast aspersions on anyone's product, and can PM you the batch #'s from all 5 buckets, 3 of which are unopened in my garage and one in my utility room which has about 30 gallons worth of salt removed from it. I didn't have this problem before, and the acros seemed to be hit or miss with the first bucket, which I chalked up to wandering tank parameters and beginner's stupidity. However, the LPS polyp bailout on corals that were extremely healthy started immediately after using salt from the first of the four caked buckets. I stumbled across this thread after someone suggessted that I should check for feedback on the salt from other users.
I'm not asking for anything other than some help. If I have a bad batch, replacement would be appreciatated. I've checked for and found nothing wrong with any other parameters other than checking for copper, which I'll do tomorrow. After that, I'm not sure where to go. Was considering using balling lite to help with the issue.
At this point, any help is appreciated, as I'm banging my head against the wall.
Regards.
Kevin
