I have been battling hair algae for a while now and I believe it's because I need to change out the filters in my RO
unit. I ordered the replacement filters for all 5 stages but was only able to change the DI
membrane and Stage 4 right now because I can't get the three large filter compartments open. So if anyone has any insight on how to unscrew them, I would appreciate it.
My main question is . . . which filter in the RO
unit filters out Phosphates? I think it is the DI
and I am hoping that with these new filters I will be able to get this hair algae under control. The filters were about 10 months old I believe.
Thanks in advance for your input.
