What I also find to be extremely strange is how the lighting effects this.
Using the full RGB spectrum the water clears up a little bit but as soon as I take it to blue only its gets worse. Is that just the lights deceiving my eyes or will the lighting add to or diminish the bacterial infection?
No... I'm inclined to think it is the light playing tricks.
Again, prepare a 20% water change. Complete the water change and rinse all mechanical filtration in RODI.
Previously, I stated rinsing in old tank water. But that would have you rinsing in infected water. Use RODI instead.
