Hey, OP here - I want to thank everyone who has come to this thread to raise some of the same, and additional, concerns they have seen with the Turkish made salt. I want to say this thread was not created to bash or discredit TM in anyway.
As a long time reefer and long time users of TM salt (before it ever got popular by BRS, it used to be the odd man out salt back in the day), when I opened a new box of Pro salt the distinctive strong acidic smell (which I have never EVER had experienced before for the 15+ years of using TM salt) hit me I knew something was different. Looking at the box I saw this was one of the new Turkish batches, and the first batch of Turkish salt I had received. After mixing it the physical properties, smell, and sludge were all new and I knew something was not right.
This then led me to searching the issue out online which I found some complaints about the Turkish made salt scattered around the interwebs. That is why I decieded to start this thread, to see if others have also been experiencing issues and for TM to weigh in on the matter. Again, I approached this first that this could of been simply a change in raw chemical that only Turkey is getting based on supply chains, etc. I was looking for TM's confirmation that yes the properties were normal for the Turkish facility, or no they are not and could potentially be a bad batch. I was initially disappointed by TM's initial response of taking a defensive stands that nothing is wrong with the turkish salt, however Lou has been very helpful and genuinely concerned. He sent me a shipping label to send him a sample of the salt, which I have along with a sample of my tried and true German made batch.
I cannot attest to any ill effects to livestock as I did not use the mixed water in my tank, the physically properties being off and enough examples I found of people with negative experiences held me off from its use. I hope with my sample, and with others that have come to this thread, TM can pinpoint the issue.
As far as a consumer prospective goes, I do share the same sentiment that others have mentioned, with no disrespect, that if I'm buying a German made product I expect a German made product. Turkey is not known for great quality standards and Germany is the exact opposite as a pinnacle of those standards. TM is a premium product at a premium price, and as a such I expect it to be made in Germany. Its like you bought a Mercedes, expecting German made, but find out it was assembled in Mexico.
