| | Re: Seachem Dosing Calculator/Chart
I used this calculator/chart for 2 years just to see how it works long term. It worked great with one minor problem. My Barclaya longifolia would sometimes have pinholes indicating a potassium deficiency and I would have to add a little extra F. Potassium. The Barclaya longifolia was the only plant that ever had pinholes. The other plants never did. I guess it needs a little more potassium than the other plants.
If you want to view the formulas used, you can use Excel's unhide feature for this. Since it is in Excel; you can customize it as needed for your application(s). You have the option of changing any of the formulas as needed.
I hope it helps you and many other people out.
