I have had high nitrate (60ppm+)for quiet a while which I am struggling to get under control.
I have been dosing NOPOX 3ml daily with weekly WC. Nitrate still climb.
My last ICP had PO4 at .1ppm but after dosing NOPOX I tested PO4 at zero(undetectable) so have been dosing Triton Phosphorus at .1-.2 ml per day and testing. Still my tests shows zero/undetectable. I assume because NOPOX is working to reduce it and it stalls again once PO4 is zero and Nitrate climbs again.
I have lost a couple of corals in the last 2 weeks (Duncan/Hammer) and now wondering if my PO4 test kit has has failed me (NYOS)
I am thinking to do a test on RODI water with a drop of phosphorus into 1 liter. This should give me a good hard blue on the NYOS test. If not I can assume the kit has failed.
Does this sound a reasonable approach to discount a questionable test kit?
This is what I have been dosing as advised by LFS
