Randy, I have been reading up on Tropic Marin's new balling method additives and Aquaforest about the importance of the ionic balance with two part dosing. I have been using your recipe #1 but my question to you is, is your recipe balanced for the slow build up of NaCl? I assume the magnesium component is not pure and will likely contain some minor trace elements. I notice that in the Tropic Marin method the magnesium mixture also contains potassium. Aquaforest does not list the ingredients in their Reef Mineral salt but along with their other additives that are recommended with their version of two part dosing they also contain strontium, potassium, iodine, fluorine as well as the minor trace elements. With all three methods, Randy's DIY Two-Part, Tropic Marin Balling salts and Aquaforest, all methods will slowly raise the NaCl level over time but from the list of ingredients only Aquaforest will raise the major and minor trace elements along with the NaCl rise making it the only true "ionic balanced" method. What are your thoughts? Is not having the trace elements in your DIY mixture going to be then end of a reef tank or will monthly water changes be sufficient in replacing the depleted trace elements? Are trace elements that important for coral coloration and growth or is it just the new trend in reefing? If I add strontium chloride to my calcium mixture and potassium chloride to the magnesium mixture and dose Seachem Reef Trace/Seachem Reef Plus weekly will that be a "balanced" method? Thank you in advance for your time and response.
