Looking for this calculator

I used this calculator on another forum and found it pretty useful for what I needed but forgot to bookmark the page

I took a screenshot of it though. Does anyone know which calc it is?

That's the "Fertilator" at Aquatic plant central. You have to be logged in to use it.

I prefer this calculator. It's far more powerful.

EI is the abbreviation for Estimative Index developed by Tom Barr. It's a fertilizer dosing technique that provides non-limiting nutrients without the need for water testing.

Here is a post on his website explaining it.

Here is my interpretation.
