Eddie:

Found this you might be interested in:

"A final scenario to consider for magnesium depletion comes into play for aquarists supplementing calcium and alkalinity using calcium chloride and either sodium carbonate or sodium bicarbonate (e.g., baking soda, baked or not, respectively). The reason that this scenario is different from the above cases is that the addition of the chloride and the sodium ions tends to raise salinity. If the salinity is then adjusted back to normal levels periodically (by dilution with fresh water), the effect is to depress magnesium faster..."

Came from here:

Helps explain what happens to the excess sodium and chloride ions and why the magnesium is depleted more rapidly. I was just drawing a blank on Saturday, sorry, and it's been buggin' me since.

Thanks Dave

Too much for me to read at work during lunch, but I will check it out this evening.

Thanks again
