Hi folks, We haven't had a nice technical topic for a while, definitely not one on chemistry. I have been trying to read up on Ionic Balance and whether the literature that I come across in random places across the web may have some merit or more snake oil. This all started when I began looking into the limitations of kalkwasser, I have only dosed kalkwasser for several years now and at this point my growth/uptake is outpacing the ability of my kalkwasser regiment to maintain a chemical balance. I ended up supplementing with 2-Part solution on top of the kalkwasser I'm currently dosing and this is when I actually took a closer look at the labels on my 2-part jugs. I noticed all the elements not found in kalkwasser: Part A ingredients Calcium Chloride, Magnesium Chloride, Calcium Bromide, Strontium Chloride, Lithium Chloride, Rubidium Chloride, Nickel Chloride, Chromium Chloride, Zinc Chloride, Copper Chloride, Cesium Chloride, Iron Chloride, Manganese Chloride, Cobalt Chloride. Part B ingredients Sodium Bicarbonate, Sodium Carbonate, Sodium Sulfate, Potassium Bicarbonate, Sodium Metaborate, Sodium Fluoride, Potassium Iodide, Sodium Selenate, Sodium Vanadate, Sodium Tungstate. This consequently lead me to look into ionic balance and how all these elements play a role so let's hypothetically say that you don't rely 100% on water changes to replenish all of your elements (I think this criteria represents the average reefer) and how the ionic balance plays out in such a system, can balance be achieved by dosing and what elements are considered essential (not to be confused with the product "essential elements") for maintaining a good balance for maximum coral growth.
