I have this haze on my front glass. I don't have algae problem other than this haze. The phosphate is at 0.06 and nitrates at 8.6. I need to scrape it off every two days.
Why is this happening and what is the best way to address it? I have been having this situation for more than a year even though the parameters have been near perfect.
Any help is appreciated.
