How to dose dry ferts.

My dry ferts will be here in a few days and I"m trying to decide what to do. I like the PPS method best but I would like to control the KNO3 & KH2PO4 a little better. ((Other tank ifno. is below.))

Will this work?

Thanks!!!

Macros
In 1 liter bottle:
59 grams K2SO4 (Potassium Sulfate)
41 grams MgSO4 (Magnesium Sulfate)
Fill with distilled water and shake well. Let sit overnight.
Dose 1ml per 10 gallons per day

Dose KNO3 & KH2PO4 according to testing.

Micros
In 1 liter bottle:
80 grams of CSM+B
Fill with distilled water and shake well. Let sit overnight.
Dose 1ml per 10 gallons per day

10 Gallon Tank
6.7 wpg - (1x15watt T-8 & 2x26watt Spiral CF's )I know it's probably not actually 6.7 wpg)
DIY CO2
aqua-clear 30
heater
1 Bag of fluorite
NPK & Plantex (ordering on-line)

Hi mattmathis,

Hopefully Edward will address this question, but my guess would be no. If the chemicals are not available in the proper proportions, problems with plant growth and algae may occur. I am under the impression that changing the concentration of one nutrient, requires changing the others.

You could try the PPS Classic dosing regimen. It is a little more hands on which might cater to your liking.

The PPS Pro is fine for the new tank I'm starting, but I have a 75 gallon tank that has been established for around 5 years and the nitrates are 40ppm even with 30% weekly water changes. And I bet the phosphates are at least high enough to get by if not all ready too high. (P test is on the way)

I simply want to dose potassium, magnesium, and trace without dosing nitrates and phosphates.

Surely some one can tell me how...
