I understand what you mean, the values i gave you are the cumulative i test in the water tank over severals weeks of dosing. In others words these are the balanced out values from dosing + water change or the residual value in the water. Not what i dose weekly.And you know these are the right quantities for your tank how? I can tell you this would not work in my tank, plants would stunt by Wednesday if I front loaded this little over the weekend... They clearly do not work in your tank - I saw your plants...
Focus on the plants, not some arbitrary numbers...
I.e nitrates amount in water are ~28ppm daily
I undersantd test might not be 100% accurate on the numbers, but it means at least there is some residual, the plant should not missing out on anything.
If we talk about the same thing @palcente, what would be your suggestion? Increasing that residual value?
P.s i have already tested by front loading around the same value on sunday on the past and be only that as the dosing. By thursday my nitrates would be at 0.
