I wanted to revisit this storyline.
We have been sitting on about 4 pallets of Turkish TMP 200g buckets for a while and decided to start seeing if it was usable. We would not use it on our client tanks, but if it’s usable in our systems…well, as you know, 4 pallets is a lot of salt.
Was the issue ever confirmed? I read some old stuff that talked about clay, then there were some allusions to it being ammonium. I actually started using some in my classroom aquarium, and have not noticed any issues with either odor, mixing dirty, or any adverse reactions from any of the coral in that tank.
Is it possible that it was just a bad batch that went out? Back when I was young and dumb (as opposed to old and dumb, as I am now), I regularly added Kent Reef Carbon to client tanks. They had a contaminated batch go out, and it wiped out most inverts in 6 client tanks that received it over the course of 3 days. That was pretty definitive contamination, but at the same time, overall they didn’t have quality issues…they just had a contaminated batch go out and I was unlucky enough to get some of it.
I’m going to start playing with it. If it was ammonium, I’m not going to worry about it, b/c I wouldn’t be doing big water changes. I’ll test and see if there is any ammonia.
I would love to be able to use all this salt for something.
