Thank you to everyone who's share their knowledge with me.
Just a quick update. My new
UV sterilizer arrived and has been in for 72hrs and my tank is crystal clear again.
Here's two pics - 48hrs ago and and about 30min ago. I put it in 3 days ago and wished I had that pic to include so you could see what a difference the Green Killing Machine made.

Before - 2 days ago

After - Today
Before my old ones died I left them on all the time. Does it mess with the balance at all leaving on all the time? Thoughts?
