Hi Greger,

LaMotte makes a kit !
I had more than 1gr/l and fishes dying when I got too far...
It was during holidays and my neighbour put every day what I ask him for !

What I can say is that if you let water run outside your tank along the glass and
that the next day you have a white deposit you have too much of something
(in my case it was K+)...

What a tank can take depends of Water changes !
If you add  X mg/l of product and change with the same frequency 1/N of your water
you can end up with max. N*X mg/l of product (when the tank consumes none of it).
No water change means INFINITY !
Changing all of it ;-) means knowing what is in the water !
In between you can choose.

Regards,

Philippe

| Thank you Philippe!
| 
| I've been wondering about how much K a tank can take.
| KNO3
| KH2PO4
| K2SO4
| There's gotta be a lot of it in the tank, but I don't know of any method to measure it. 
| 
| Is there a way (formula) that I can use? 
| A value from something else I'm testing for and enter it into a formula to derive how much K I have in the tank?
