I want to add microalgae directly to an aquarium system. The microalgae will be fertilized with a modified F/2 formula that contains NaNO3 and NaH2PO4·H2O as the 2 main macro nutrient ingredients as well as significant amounts of Na2EDTA·H2O.
The NO3 and PO4 can be sequestered and exported via the microalgae and other pathways, but my main concern is the accumulation of sodium (Na) over time.
I calculate that with 10% monthly water changes (0.333% per day) the Na concentrations will creep up to and level off at about 2.57% above normal levels. (From 10,800ppm to 11,078ppm Na).
My question are
1) just how high of an imbalance of Na relative to other ions in the aquarium water is acceptable?
2) What are the repercussions of such an imbalance? I assume similar, raised Na, situations have occurred with significant additions of Baking soda (sodium bicarbonate) added over time.
3) Are there other solutions to this problem (other than larger water changes)?
Also want to note that the addition of Chloride via the algae fertilizer seems insignificant… 24 to 2284 (24 moles Chloride to 2284 moles Sodium).
I hope this question makes sense and thank you in advances for any advice.
