I test for nitrates and phosphates test kits from redsea.
My nitrates show that they are at 0.00 and the phosphate test I am not getting no chemical reaction in the test. Hair algae is starting to grow more. Can something else be causing it. I have a new rodi unit and do a water change every 2 weeks about 20%. What else can I do?
