Me again!
Rather than editing my post above (#20), I really would like to resurrect this thread even though it was started over four years ago (by GlassWalker). The thread focused on potassium but the OP's question concerned sodium. There appears to be some uncertainty about sodium in planted tanks - both for plants and fish. Seachem has the following to say about their Equilibrium product geared towards RO/DI water remineralization:
"Unlike competing products, Equilibrium™ contains NO SODIUM CHLORIDE. Both sodium and chloride are not rapidly depleted elements in a planted aquarium, and, in the case of chloride, can do more harm than good. Competitors’ products generally contain primarily sodium chloride (because it is inexpensive), which will raise the electrolyte levels for fish, but can be detrimental to plant growth. In addition, sodium is not a contributing cation to GH levels. Equilibrium™ contains only calcium, magnesium, and potassium salts, which aid in fish metabolism, but are also highly beneficial to plant growth".
Would anyone care to comment?
