Hara is right, but the cyano
may give low to no phosphate readings, since the cyano
loves that stuff (IME, my phosphates were only reading around .1, nitrates were undetectable and my tank was covered in cyano
). What kind of filter are you using? I just successfully wiped out my cyano
. If you update your "my info" with your tank size/equipment/critters, that would be helpful.
water "checking out' is probably not as acurate as you think
Can you post test results?
That link that Fluff sent was helpful for me. I ended up doing a few other things.
