Salts

[hardcz]

Care to elaborate on that?

Mostly because my views on life make me right and everyone else is wrong or has ideas that I could adopt as my own.... but yea

I wrote this up at another site long ago....

I found the following at reefcentral

These are not any official numbers, but should give everyone an idea where the salt mixes should be after mixing.

Here is a list of what I measured for the big three in a number of the salt mixes we use today. This is intended as a guideline and I, in no way, guarantee these figures. All I can say is they were all tested under the same conditions, with a number of different brand test kits, using the same methods for each test. I believe these numbers are reasonably what you can expect from these salts mixed at 35 ppt or 1.0264

And then some numbers we've gathered from manufacturers

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):
Alkalinity
Calcium
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.
