I have tried a couple different salts recently. I’ve been using tropic Marin pro reef for a couple years but when I couldn’t get it a reasonable price I started using Red Sea blue bucket. No issues there. I’m going to try Fritz rpm because I can get it at wholesale cost and it’s a good salt with parameters not far from what I keep my tank at. Problem is I got about enough salt to make roughly 20 gallons of both Red Sea and Tropic Marin each. I usually make about 40gal at a time, let it mix up and use the whole batch for my water changes. Can I mix any of these salts in a batch? I’m not worried about the parameters or the actual salt my concern is things like different anti caking agents.
