Stock solution calculator for phos/nitrate

[nigelmansell]

Hi

I want to make stock solutions up using potassium phosphate and potassium nitrate.

What I want is to make the solution the right strength that dosing e.g. 1ml raises the PPM in my tank by the specified amount (lets say 0.01 PPM for phos and 1ppm for nitrate).

Does anybody know a calculator which will do this?

I have searched this site, and used to have a really good F/W planted tank one, but the site is dead

Thanks

Absolutely typical, after searching for weeks I find one almost immediately after posting.

Here it is for anyone with the same requirement...

I see you already found one. Here is another one that I keep bookmarked. http://rotalabutterfly.com/nutrient-calculator.php It has a lot of different dosing products and strategies implemented.

For making it or using it?

If you make my DIY or use BRS, you can use this calculator:

FWIW, my DIY #1 is equivalent to 375 g of sodium carbonate per gallon of fresh water.

I guess I'm not sure what you are suggesting.

Personally, I'd make my DIY and adjust the dose to match. My DIY contains 375 g/3785 mL (1 gallon) = 0.099 g/mL.

So if you want to dose 20 g equivalent, you dose 202 mL each day.
