This is just a calculator based on Seachem's recommended dosing plan
. It really makes the math easy. Seachem's dosing chart is a bugger to work with if you have to calculate your dosing by hand. Actually, it is a weak system compared to some dosing plans. We have to remember that Seachem had these products out before many of us were purchasing dry ferts.
We normally add N, P, K and Trace Nutrients like Seachem's Flourish, Tropica's Plant Nutrition liquid, CSM+B etc. Some add extra Fe or Flourish Iron. Some add GH Booster or Equilibrium and some add Baking Soda or Alkaline Buffer. Seachem's Flourish Trace is the one that is mostly water and can be omitted as mentioned above.
Please don't get Seachem's Flourish Trace
mixed up with their Flourish
. Flourish is very useful.
