K dosing was only an example ,I was just trying to figure out the chart.
I realise now that each tank has its own biomass size and variety ,hence nutrient need ,and also the competition between each species present in a specific tank.This can vary ,way beyond ,thanks for the heads up.
I imagined Estimative Index ,as dosing more than enough ferts for a tank that's packed with plants ,as many as you can squeeze in.
I have a Tetra PO4 drop test ,I will do one after dosing Flourish P.
I know I have 20ppm NO3 in my tap ,I will not dose it ,but I didn't know you can actually test K ,and that was the reason people always kept it in high ppm ranges ,just to make sure some will be left at the end of the week.
Which brand makes K tests ,at least worthwile ones ,not ultra-accurate?
