Kent Marine 00412 Tech M Magnesium, 16-Ounce Bottle

Tech M Magnesium supplement is a ionically balanced product which will safely raise the magnesium level in any marine system without upsetting the ionic balance of the system. Tech M is very concentrated, containing over 70,000 ppm of cationic magnesium, and is nitrate, phosphate and gluconate free. If you have trouble maintaining calcium or buffer level, check to see that the salt mix you are using has seawater level of magnesium. To save money and increase dissolvability, some manufacturers of popular newer salts have included only half the level of magnesium necessary in their sea salt mixes, resulting in low calcium solubility and poor buffering. Tech M Magnesium supplement will provide the magnesium left out by salt manufacturers or increase the magnesium level in any system. This will provide for easier maintenance of alkalinity (buffering capacity) and calcium level.
