I know many of you think that Tropic Marin salt is too expensive. I hear ya, but I still like using it. So this post is really for the folks that use the Tropic Marin Pro-Reef Salt Mix or have been considering testing it out. The last time I bought salt I ended up making the mistake of buying the Tropic Marin Classic Sea Salt Mix instead of the Pro-Reef mix. I don't normally test alk, calcium, and magnesium for my fresh salt water mix but since I bought the Classic version I wanted to know how much I needed to adjust the fresh saltwater as to not make big changes or drops in my tank parameters when I do the next water change. Tropic Marin states that alk, calcium, and magnesium should be around 9-10 dKH, 380 ppm and 1260 ppm respectively for the Classic mix.
When I tested the first batch of fresh saltwater, I found a pleasant surprise. Here's what I measured for the Classic mix:
Salinity: 1.026
Alk: 9.6 dKH (Hanna)
Calcium: 450 ppm (Red Sea)
Magnesium: 1440 ppm (Red Sea)
This matches almost exactly what I keep my tank parameters at. I will test each batch of saltwater for each water change to make sure there is consistency. So FYI for those that use Tropic Marin Pro-Reef Salt. As an option to the Pro-Reef salt, it's looking like The Classic version has also reef like parameters for alk, calcium, and magnesium...AND, it is slightly cheaper at BRS.
