Dosing Instructions

 

Dosing Instructions-

While there are many different dosing methods, the two most common are EI (Estimative Index) and PPS-PRO. People commonly ask which is best, which happens to be a nearly impossible question to answer.

What works best for one tank, might not work best for the next.
Each tank has different components that will determin which method works best for your needs.

These dosing instructions are intended to be used with tanks with high lighting and CO2. If you have questions about lighting or CO2 please join the facebook aquarium fertilizer discussion group HERE....

50% Water Change on Day Seven

*If you are dosing Iron Chelate dose at 1/4-1/3 the amount of it that you do CSM+B or Millers Microplex.

*Dose Iron Chelate at the same time you dose your micros.

For the above amounts you want to dose the macros(kno3, kh2po4, and k2so4) and the micros(CSM+B or Millers) all 3x per week on alternating days.

An example of this would be the micros on Monday, Wednesday and Friday.
The macros on Tuesday, Thursday and Saturday.

Then a 50% water change on Sunday followed by adding the Gh booster.

This 3x per week dosing is suggested for high light tanks with co2.

If you have medium light tank try starting out dosing 2x per week, low light tanks can be dosed 1x per week.

If in the example of the medium light tank you dose 2x per week and you start seeing deficiencies then up the dosing to 3x per week.

The EI method is based on the thought that excess nutrients will not harm anything in the tank.
So even if you had a low light tank and were to dose 3x per week at the full amounts, as long as you kept up with the 50% weekly water changes it would not cause any problems.

EI Nutrient Solution-

Credit for this section goes to Zorfox

There seems to be a lot of confusion about how to mix nutrient solutions.
Below are basic recipes for solutions or dry dosing for common US tank sizes.
Every solution or dry dose will provide the exact levels shown below.
These should be dosed 3 time per week based on high light and CO2 injection with a 50% weekly water change.

Low light and no CO2 simply use 1/3 of the dosing listed with the same 50% weekly water change.

 

*Since KNO3 (potassium nitrate) provides significant potassium, K2SO4 is optional.

The K2SO4 doses listed below provide 2.2 ppm of potassium which raises potassium to the full EI level.
This is usually not necessary.

 

Target Concentration Levels
Macros
NO3 7.5 ppm
N 1.694 ppm
PO4 1.3 ppm
P 0.424 ppm
K 5.3 ppm (7.5 ppm with additional K2SO4)
Micros
Fe 0.5 ppm
Mg 0.107 ppm
dGH 0.025 ppm
Cu 0.007 ppm
B 0.061 ppm
Mn 0.143 ppm
Mo 0.004 ppm
S (0.917 ppm with additional K2SO4)
Zn 0.028 ppm

 

*Mix the amounts given below for your tank size into 500ml of water, preferably R/O or distilled. Doses vary as listed depending on tank size.
NOTE: You will need two bottles, one for the CSM+B and one for the rest. It is not generally a good idea to mix CSM+B and the others in the same bottle.

PPS-PRO dosing Method-

*The following mixing instructions are based on using (2) 500ml dosing bottles, using a gram scale to measure the dry fertilizer:

Add the following into the first bottle. (this will be your Macro bottle)

Amount: Fertilizer
32.5g KNO3
29.5g K2SO4
3g KH2PO4
20.5g MGSO4

 

Add the following into the second bottle. (This will be your Micros bottle)

Amount: Fertilizer
40g CSM+B

 

Next fill the dosing bottles to the 500ml line with RO or DI water.

Dosing instructions-

Dose both the Micros and the Macros at a rate of 1ml per 10gallons seven days a week.
