i hear it's a good salt but i suggest to you to buy the tropic marine pro (expensive but worth the money)
i add one more tank and i put in new ro/di water when i add the salt to the tank i check the parameter and here is the result that i get after 3 day without adding nothing.
calcium - 400
dkh 8.6 alk 3.09
ph 8.1
the salt level was at 1.025.
i use before that reef crystal but never get to this result anyway this is just suggest .
