What works best for one tank, might not work best for the next.
Each tank has different components that will determine 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.
PPS-PRO dosing Method
The following is the older (and in my opinion better) version. For the new official version click HERE.
*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.
