These set of frequencies focus on nitrogen.
Based on the old model that chemical bond is like a particle where the bond length is its diameter. The bond can be set into resonance by a frequency,
fres=0.122cBL
or one that is at integer division of fres. For example, the frequency to set N−O bond in nitrate to resonance was calculated by,
fres=0.122∗299792458127.3∗10−12
where the length of the N−O bond is BL=127.3pm
fres1015=0.122∗299792458127.3∗10−12=287.311Hz
where fres is reduced to the audio range (because an audio system is used to produce the required frequency) by a factor of 1015.
With sufficient energy , the bonds are broken with the formation of bi-atomic gas, O2, N2 and H2. The frequencies seem to work as the aquarium clouds up with tiny bubbles that dissipate after the frequencies are removed. An air pump aerator is better at removing the tiny bubbles than a filter.
Good night...
