Many thanks to those that joined our webinar.

One of the highly important topics that came up was the question of imbalances and as the slide show was clear to show, once explained it makes so much sense. I will try my best to put some of that info here.

If anyone highlights an inaccuracy to what I have written please let me know and I will happily address that in the thread openly.

Hearing about the relationship between the ions of Calcium chloride and sodium Bi-carbonate was fascinating especially how the coral polyp takes in the calcium ion from the calcium chloride element and the carbonate ion from the sodium element and what is left behind is your imbalance.

Left behind is sodium from the Bi-carbonate and chloride from the calcium, these two together of course make sodium chloride, and here lies the imbalance in 3 part, all of a sudden you have extra sodium chloride with no other elements attached to it floating around in your tank, and by doing a water change you are only removing the percentage of that water change of the imbalance.

So if you are dosing 2 or 3 part light systems and rely on water changes alone to address the imbalance you are only removing for example on a 10% water change, 10% of that imbalance.

Now - by adding into the mix Part C the remaining sodium chloride has something to balance it which includes the 70 trace elements

Now of course there is an argument that this system too raises your sodium chloride level, and yes you are right, BUT and here is the defining factor, it is doing it in a balanced format in the same way you would be doing by adding more sea salt to your system, because it is balanced there is no ionic risks, and even the most minimal water change would cater for any salinity rise, however due to being in balance and such a very low level this is not an issue, where as an unbalanced system with just sodium chloride floating about is.

What is an issue however are 3 part or light systems that allow for free amounts of sodium chloride in your system with nothing to balance it allowing for a complete imbalance that can not be addressed wholly by water changes as you only remove the % of water change and as such only remove that % of imbalance.

There is only one way to keep a system in balance when dosing calcium and sodium Bi-carbonate and that is to add in proportion NACL free salt. (Part C)

To make the point clearer, the very first original Sea Salt mix from Tropic marin that still to this day forms the basis of all their salts is a 100% mixture of A B and C of the Tropic Marin Balling system together!

So there is no argument chemistry in itself proves it, if you dose a system with nothing to balance the excess NACL you create an imbalance, and this is where part C comes in which is made up of everythign you find in a sea salt mix including all trace elements without adding additional NACL, hence the term for part C as NACL-FREE sea salt. But lets be clear Part C is not just magnesium as in every other other 3 part system, it is the whole bells and whistles found in sea salt as stated before WITHOUT any NACL component.

This is why Tropic marin balling from the inventor Hans-werner balling is so popular to those that care about doing this 100% right.
