Stable nutrient dosing using hobbyist test kits

[Dennis Wong]

I fully agree with the concept Rocco !

But when you don’t know about that and you follow the advice of say APT fertilizer for exemple, it say to dose 3, 4 times or every days of the week , but not replenish what the water change remove !

You know what i mean ?

APT3 aims to be zero bound so there is no need to replace nutrients during water changes. APTe has an updated page on how to use it precisely, whether on a zero bound system or at an elevated level.

Doh! I've been double dosing APT3 on water change days since the start, and I dose every day.

If the aims is to be zero bound Dennis, what is the logic of the very high potassium level in your product ?

From previous ICP testing on my old tank, potassium is consumed at a rate around 0,4 to 0,6 ppm per day when my no3 consumption was between 2 and 3 ppm per day.

So if your product introduce around 2,5 ppm K+ per day, there will be an accumulation of k for sure ?
