Been battling hair algae and cyno, not horrible, but annoying. Was doing everything by the book and running phosphate sponges galore but could never get my PO4 below .25 for very long.
Since i had recently changed the filters on my r/o unit, I never until last night check it. Well lo and behold the PO4 of my r/0 water is guess...
You got it .25.
Does this mean I need to change the membrane? I believe its the only thing left.
I am take a water sample to my lfs tonight to test for TDS.
