Hi,

I need 315mg to reach 2ppm in my 29g low light.
Something lile a 1/32 teaspoon. But there is any simple way to dose it?

Something like a mix 1/2teaspoon with 250ml water and dose 15 ml of this solution?

Can I dose it once for week and keep stable 2-3ppm? Or I must dose it 3x times?

Thanks

Yes for the just add this much water to...but I can't calculat it yet so I'd be guessing based on my 10g. And actually I do dose 1/64 tsp one week and 1/32 tsp the next.
But it will be regulated by your WC. As in once a week after the WC.
There are at least a couple of them on here who know a formula for it and I'm sure one will jump in before too long.

Before spending too much effort, there may be another factor to consider.
I found EI was a place to start but doing a 50% water change was not enough to keep my phosphate from creeping gradually higher and higher. Mine got off the charts before I found it. I got into an area where I had to do massive frequent water changes to get it back down. I no longer use ANY K2PO4. I get plenty from food or other sources. Maybe you don't really need to do the 1/32 measurement anyway?
