I’ve tried many salts over the years. I was a Tropic Marin guy for a very long time then discovered Red Sea Coral Pro 17 years ago. I tried others but nothing has been as good for me as Red Sea Coral Pro.
I was looking at Red Sea and Tropic Marin salt mixes comparing quality. I have always used Instant Ocean but was curious if these other salts really make a difference
30 years ago the difference between Instant Ocean and Tropic Marin was night and day. Now it is a smaller gap. I e tried Seachem Reef Salt as well and liked calcium and magnesium levels but it had a really bad residue. Red Sea Coral Pro mixes fast, is more stable than they advertise, and has great levels. I still use it in my FOWLR because on
Amazon the Coral Pro is the same price of cheaper than the regular.
Think of Instant Ocean as a bare minimum salt. For that purpose it is great. If you are seek something better and don’t want to break the bank I really like Red Sea Coral Pro.
