Introducing the Advanced PPS-Classic Calculator for Aquatic Plants.

The PPS dosing system has been shown to be a reliable method of providing required nutrients to many hobbyists in a variety of applications, lighting conditions and size of aquariums. With time and experience we have developed this Calculator to further improve and simplify dosing procedures. Bellow are descriptions and illustrations with examples on how to use the calculator.

Download, PPS Dosing Calculator for Aquatic Plants or http://ca.geocities.com/pps@rogers.c....plants.37.xls

On the left side is the Entry Data section and on the right side the Results. A helpful message pops up when an input cell is highlighted. Note that only the white highlighted boxes require input from you.

Enter the size in gallons or litres, in the Red circle highlighted above.

Next, in red circle is the Present Daily Dosage. Enter the ml and drops of all solutions that you have been dosing on a daily basis

Next is the tested period. Enter the length of time between testing in number of weeks. Note that the calculator requires the number of weeks between testing periods to determine the amount of nutrient uptake by your tank and to determine your daily dosage requirements. Accordingly, the tested period should correspond to when you tested and the test results you will input in the levels after period.

Enter tested levels before period in ppm. (this corresponds to your present tank reading)

Enter tested levels after the period in ppm as indicated. The testing period should correspond to the "Tested period" entered above.

Enter the levels you want to have in your tank.

Read the new quantity of solutions to be dosed daily. Quantity is in mls or drops or combination of both. Then adjust dosing accordingly and enter these revised values in the "Present daily dosage" section.

Read the present daily dosed levels in ppm.

Read the present daily uptake by plants in ppm. For information purposes only.

Read the new daily dose levels in ppm. A result of the Next daily dosage. For information purposes only.
