What would you expect NO3 to be on the third day of EI dosing?
i have a 36 gal long and have been dosing EI for around a month. i'm injecting co2 (non diy) and have 2 wpg light with good reflectors.
off of tom barrs site iv'e been dosing 1/4 tsp no3 and 1/16th tsp phosphate (dry) on day 1. on day 2 i'm dosing micro's according to his recomended instructions.
i figured i would follow this religiously for a month or so and then start adjusting up or down as necessary. this morning i did my first NO3 test (i did water change on sunday and dosed macro's, dosed micros yesterday) and my no3 read just above 0. maybe 5ppm.
i thought i might have been dosing too much but after the reading i was surprised to see it almost gone from my tank. i did add API's stress zyme on sunday (only thing iv'e recently changed) other than that my tanks only moderately planted with crypts and stem plants.
curious what you all are getting for readings for fert levels at such an interval in the dosing schedule? would you expect it to be much higher? from what i understand so far about EI i was expecting it to be at least 20ppm or so.
also i have noticed some of my plant leaves (quite a few of the stem plants, hardly any of the crypts) are chlorotic and yellowing from the edges on the older growth.
