I have been using TMPR for years, and it is a great salt.
MG is not 1300 PPM but nor is Natural Salt water in oceans ...
KH is 7, but so is the oceans ...
and so on.
I have now switched to KZ, and that is even a better salt, but way too expensive.
Eric,
to detect if there has been a mistake from our side, we need the batch number which can be found stamped on the underside of the lid. We did get only few emails regarding low alkalinity and most were from customers that did get alarmed by threads in this forum.
I can read some postings that customers have bought PRO-REEF and now, alarmed by this thread, are annoyed about a KH of 7° when in fact we never claimed anything else but being close to natural nevels.
A KH of 7° means in my eyes, the salt is at its optimum value, no need for any change. If you believe something different you have to take a different salt, maybe the classic Tropic Marin Mix.
The problem is, you cannot have everything, a salt with high calcium, high KH and free of synthetic chelators because you already get saturation with calcium carbonate at natural levels. If you elevate calcium and KH over natural levels you will get precipitates if you don´t use synthetic chelators. So you have to make your decision what you want.
IMHO the difference is in the levels of KH in the US in comparision to Europe. While in Europe in the last decade the insight has spread that it is not advantageous to elevate KH above natural levels, at least not in low nutrient systems, in the US elevated KH levels are still widespread and believed to be advantageous.

What is better about it?
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
CA was tested at around 440ppm with the bucket of 5dKH.
