Macros + Micros fert package question
This is probably an innocent question, but here it goes:
I have a (200G) planted tank (with fish!). So far, i am only dosing Excel and KNO3 daily. For 'showering' my terrestial plants i use a fully soluble NPK 26-5-12 + 2 + micros.
The full composition reads (%)
Total N= 26: (Nitric = 11) (ammoniacal = 8.5) (ureical = 6.5)
P (P2O5) = 5
K (K2O) = 12
Mg (MgO)= 2
B = 0.01
Would this be suitable to use as a supplement? lets say 2x a week and always dosing to an ammoniacal N concentration < 0.1 ppm. Something like:
200G = 750 ltr
0.1 ppm of ammonia in 750 ltr = 0.075 g
Total fert (at roughly 10% concentration of ammonia) = 0.75 g (1/6 tsp).
Can i do something like this? or will the presence of ANY ammonia at all create major problems or hurt the fish?? i understand plants prefer ammonia/urea over nitrates, so ammonia should be quickly taken up by plants; also the micros concentration will be pretty low anyway... so maybe its not even worth doing at all (?)
Thanks in advance!
