GHA and LEDs

[mark429]

I know the light spectrum in LEDs are very close to the sun and direct sun light can be a factor in GHA. That being said do you think that have my lights to bright be causing HA?

Did you have different lighting before and then notice HA after going to LED?
Have you tested your phosphates and nitrates?

 

[mark429]

No I have always had LEDs but I also have always been fighting some type of algae. My phosphates are under what my test kit can detect but my nitrates are alittle high, I have been doing a 5 gallon water change every other day to try and bring it down, but it has seemed that even when my nitrates were down I had some HA

Yeah I don't know if its related I just can't seem to get ride of it, I am running a brs dual stage with carbon and gfo
