ok Luis...on my second cup of coffee..I used red sea salt years ago, blue vs black main difference is Alk # 8vs12.. as far as the Red Sea product you posted "trace colors" , I never used this product. After some reading, yes seems a bit "confusing" with package design, gives you idea your dosing CA. Which you are not using this product. Seems there are 4 products to this line A,B,C,D, which directions say based off CA use by tank or CA you add to tank. So for every 20ppm of CA you have to correct to get to your desired CA level maintained you add 1ml for every 25 gallons of tank water.
So my understanding of the reading I did, you dose this every time you make a correction to CA.
So changing salt brands will not matter, since this product wants you to dose based off CA use or the CA amount dosed.
I like things simple, I switched to Tropic Marin A- and K+ recently to see how the tank likes it since the prior brand I was using, I found the tank was not responding to it after almost a year.
Plus I am carbon dosing a diy formula of vodka, vinegar and rodi H2O.
Hope this helps, please remember this is only my take on the product and there maybe other views.
