Youre right, I really need to calibrate the kit. Can RO water be used?

I don't see why not, but am not sure. Here is a thread that details how to do this...

Hi,

How accurate are the test kits? Have they been calibrated against a know solution?

Just want you to be careful of stopping all dosing based on an incorrect measurement. This has gotten all of us at one time or another...

I thought more about this, and instead of stopping all together, I halved what I was dosing, and am writing down levels on a chart daily. I suspect a fouled up test kit, as the levels read the same as yesterday still, no increase or decrease with no dosing or feeding (10ppm NO3, 1ppm PO4)
