Hi BRS, I believe you have had the Turkish salt before that. Per Tropic Marins website, the news of the Turkish facility was made public in April of 2021. However,
"The first 20 containers of Tropic Marin salt were shipped at the beginning of the year."

I receieved a 200gal box the beginning of April, ordered March 30, and it was from Turkey. I thought nothing of it that the salt was bad at that time, although there were red flags - slime left in the mixing container and the mixed salt had an oily film on the surface. That oily firm then also was on the water surface of my tank. I had months of issues loosing corals and unable to figure out why. ICP was clear, tore all equipement apart looking for rust, sent bacterial biome analysis in, etc, etc. Never once did I think that my salt - the gold standard of salt - who only uses pharmaceutical grade ingredients - was the culprit. My tanked began to rebound after switching to a German made Tropic Marin salt - my coral death has stopped, my SPS that did survive began to heal, and my LPS began to grow again.
I feel betrayed by Tropic Marin that I put my trust in them and paid a premium for German made, high quality ingredients and I got a cost cutting, less than standard, product instead. I have a bag full of dead coral skeletons that I can 100% attribute from using the contaminated salt. I am also upset with myself for not connecting the dots sooner that it was the salt that was killing my tank. Only after receiving a second Turkish box later in the year, that was even more contaminated than the first, is when I started realizing it was the salt.
