I might stop being a cheap butt, and actually try it. Does that mean I should expect even higher PO4 than the 2 I am showing?The Salifert test is not fine enough to accurately measure phosphate.
Only Hanna has ever worked for me.
What is the testkit for PO4? If it's Salifert, those are kind of trash. RedSea PO4 testkit is much better. At about .7 the salifert test kit returns 0 to give you an indication. The NO3 etc. are fine, but the PO4 not so much for some reason.I just retested, and same results.
I second thisThe Salifert test is not fine enough to accurately measure phosphate.
