Does anyone know the difference between the two salts? And could you tell me the specs of both salts? cal, alk and mg

Thanks,
Billy
 
from what i've heard and seen online

Tropic Marin Pro Reef was designed for reefs that tend to acquire a high alkalinity after years of using calcium reactors and kalkwasser. Keeping a lower alkalinity has been found to allow corals to better absorb calcium. Depending on the values of alkalinity in your reef , it might be best to use Tropic Marin instead of TM Pro Reef, or vice versa.

In slightly different terms, the ONLY good reason for using Tropic Marin Pro-Reef is if the alkalinity in your tank is continuing to rise to an undesirable level and you don’t want to contribute to that rising level with water changes. It is important to note that using Pro-Reef will not lower your alk but will not contribute to the rise as the original formula might. That slightly higher levels of Mg and Ca in the Pro-Reef are NOT a reason for using it because you are adding so much Ca and Mg on a daily basis anyway to your tank
 
i emailed them that same question, here's my response. keep in mind the reply was from march 2005, so i'm not sure the formula is still the same.

"Hi,

while our original Tropic Marin Sea Salt has about 380 ppm calcium, 1250 ppm magnesium and an alkalinity of 9Ã"šÃ‚° dKH, our PRO-REEF salt has 450 ppm calcium, 1350 ppm magnesium and an alkalinity of 7Ã"šÃ‚° dKH at a salinity of 35 psu/specific gravity of 1.0264. These are the only differences and as you see they are not big but substantial.
It is no problem to switch from the original Tropic Marin Sea Salt to our PRO-REEF salt by just beginning water changes with the PRO-REEF salt.
The benefit from the higher calcium and lower alkalinity is that it is easier to maintain a high calcium level which supports coral growth and photosynthesis as new scientific investigations show.
