A big THANK YOU to Mr. Ekus for his prompt replies and invaluable information!! It is appreciated!! :thumbup:


Per my conversation with Lou Ekus today, I can hopefully explain the true differences between Tropic Marin and Tropic Marin Pro Reef J
Note: Mr. Ekus has ‘read and approved’ the following. If you have questions, contact Lou Ekus, Director of US Operations, Tropic Marin USA, 44 Center Street, Montague, MA. 01351, voice: 413-367-0101, fax: 413-367-0144, www.tropicmarin-usa.com.


There are ONLY three differences between Tropic Marin (TM) and Tropic Marin Pro Reef (TM PR):
  1. Alkalinity
  2. Calcium
  3. Magnesium
ALL other components (70 trace elements and major salts) are exactly the same.

Tropic Marin at a specific gravity of 1.024 has:
  • 9-10 dKH
  • 380 ppm Ca
  • 1100 ppm Mg
Tropic Marin Pro Reef at a specific gravity of 1.024 has:
  • 6.5 – 7.0 dKH
  • 420 ppm Ca
  • 1350 ppm Mg
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.
