The most accurate Aquatic plant fertilizers

 

Chemicals & Dosing

The elements plants need are available as safe chemicals that are simple salts, called fertilizers. They are in essence dissolved natural rocks similar to mineral water drinks. These fertilizer chemicals have been produced and used by agriculture and horticulture industries to grow plants for decades. The aquarium fertilizers are not different for the reason that almost all are made of the same chemicals. The only difference is in the application technique.

FAQ

What chemicals do I need to order?
K2SO4 Potassium sulfate
KNO3 Potassium nitrate
KH2PO4 Monopotassium phosphate
MgSO4 Magnesium sulfate
CaSO4 Calcium sulfate (optional)
TE Trace Element Mix, (2% Mn, 7% Fe, 0.4% Zn, 0.1% Cu, 1.3% B, 0.06% Mo) or CSM+B Plantex

Where can I get the chemicals from?
There are many options where to get the chemicals.

MgSO4 is also available as Epsom salt in Drug Stores, Walmart and Pharmacies as bath salt.
Trace Element Mix can be substituted by any local fish store good Trace Element product containing the same elements. (2% Mn, 7% Fe, 0.4% Zn, 0.1% Cu, 1.3% B, 0.06% Mo)

How long will dry chemicals last?
There is no expiry date on dry chemicals. As long as they are kept dry in sealed bags they are ok.

Can I mix chemicals together?
Not recommended unless specified by Solutions Recipes.

How often do I dose?
Both, PPS-Classic and PPS-Pro are designed to be dosed daily at the same time. Just like feeding fish, feeding plants.

When do I dose?
The best time to dose is anytime before lights go on so the nutrients are available for photosynthesis. Daily dosing before lighting period starts, helps maintaining better balance, higher plant uptake and healthier plants.

Can I dose Macro and Micro at the same time?
Simply dose both at the same time into moving water.

How much do I need to dose?
PPS-Pro dose is 1ml per 10 gallon or 40 litre aquarium of Solution #1 and the same for Solution #2.
PPS-Classic dose is variable depending on PPS-Classic Dosing Calculator results.

Are PPS-Classic and PPS-Pro suited more for lighter planted aquariums, what's the difference?
Both systems can support lighter planted, heavily planted, low light and high light conditions.

PPS-Classic dosing quantity is determined by the PPS-Classic Calculator. The calculator needs to know a dosing period (one or more weeks or months), NO3 and PO4 water column levels at the period start and the period end. Then the calculator result gives the next dosage quantities needed to reach the chosen target levels. Additional benefit is the output statistics like, Present daily dosage in ppm, Present daily plant uptake in ppm and Next recommended daily dosage in ppm. It is a highly flexible system with analysis that can maintain any water column levels.

PPS-Pro is a simplified version taking into account most common planted aquariums. It works well when common sense conditions are met. Expected is a heavily planted aquarium with reasonable fish load. An aquarium with one Cryptocoryne and a Goldfish will not work smoothly. Also, daily dosing before lighting period starts, helps maintaining better balance, higher plant uptake and healthier plants. For lower light aquariums use half the recommended dose, for medium light use recommended dose, for very high light use double the recommended dose. Although some monitoring of NO3 levels from time to time helps to determine better dosing quantity. This system can maintain very low, medium or very high water column nutrient levels as desired.

What do you recommend for the fastest plant growth with water changes?
Easy, no worry approach. Dose PPS-Pro Solution #1 and PPS-Pro Solution #2 at the same time daily for a week, then 50% water change.

Low light:
PPS-Pro Solution #1, 0.5ml per 10 gallon or 40 litres
PPS-Pro Solution #2, 0.5ml per 10 gallon or 40 litres
Water change 50% once a week
This forms water column nutrient levels of 7 ppm NO3, 0.7 ppm PO4, 9 ppm K, 0.7 ppm Fe(TE), 0.7 ppm Mg.

Medium light:
PPS-Pro Solution #1, 1ml per 10 gallon or 40 litres
PPS-Pro Solution #2, 1ml per 10 gallon or 40 litres
Water change 50% once a week
This forms water column nutrient levels of 14 ppm NO3, 1.4 ppm PO4, 18 ppm K, 1.4 ppm Fe(TE), 1.4 ppm Mg.

High light:
PPS-Pro Solution #1, 2ml per 10 gallon or 40 litres
PPS-Pro Solution #2, 1ml per 10 gallon or 40 litres
Water change 50% once a week
This forms water column nutrient levels of 28 ppm NO3, 2.8 ppm PO4, 36 ppm K, 2.8 ppm Fe(TE), 1.4 ppm Mg.
