Our PPS-Pro Fertilizer Pack … Just Mix & Dose

Our PPS-Pro Fertilizer Pack … Just Mix & Dose

It’s ready to go…our new PPS-Pro Fert Pack is everything you need to get started with the Perpetual Preservation System (PPS) method of fertilization. The PPS Pro method is a convenient, low maintenance method of fertilizing your planted tank.

Our PPS-Pro Fert Pack includes:

  • Two 500mL Fertilizer Dispensing Bottles
  • Plantex CSM+B (trace elements)
  • Potassium Nitrate KNO3
  • Mono Potassium Phosphate KH2PO4
  • Potassium Sulfate K2SO4
  • Magnesium Sulfate MgSO4
  • dosing pipette


What you will need to get started…

  • our PPS-Pro fertilizer package
  • distilled or RO water
  • a digital scale


Preparing the fert mix in the 500mL dosing bottles…

The following solution recipe is based on the use of two 500mL bottles. Before starting, we recommend to boil the plastic bottles to sanitize them.

Step 1.

Bottle #1 – use your digital scale to weigh the following ferts, then place dry contents in bottle:

  • K2SO4 – 29.3 grams
  • KNO3 – 32.6 grams
  • KH2PO4 – 2.9 grams
  • MgSO4 – 20.2 grams


Step 2.

Bottle #2 – use your digital scale to weigh the following ferts, then place dry contents in bottle:

  • Plantex CSM+B – 28.6 grams (Trace Elements (TE) recipe updated 4/11/2016, previous recommendation was 40 grams)


Step 3.

Fill both bottles with distilled or reverse osmosis (RO) water, up to the 500mL water level line. Screw on caps tightly and shake well. Let the mixture sit over night until dissolved completely.

How to dose the mixture…

Bottle #1 Macros: daily dose of 1 mL per every 10 gallons or 40 litres of aquarium water. Dose daily, prior to your aquarium lights turning on.

Bottle #2 Micros: daily dose of 0.1 mL or 2 drops per 10 gallons or 40 litres of aquarium water. Dose daily, prior to your aquarium lights turning on. (updated 4/11/2016, previous dosing recommendation was 1 mL per 10 gallons)

(1 ml = 20 drops)

How to do PPS-Pro with water changes?

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 or 10 drops per 10 gallon or 40 L
PPS-Pro Solution #2, 1 drop per 10 gallon or 40 L
Water change 50% once a week
This limits water column nutrient levels to 7 ppm NO3, 0.7 ppm PO4, 9 ppm K, 0.7 ppm Mg, 0.07 ppm Fe(TE).

Medium light
PPS-Pro Solution #1, 1ml per 10 gallon or 40 L
PPS-Pro Solution #2, 2 drops per 10 gallon or 40 L
Water change 50% once a week
This limits water column nutrient levels to 14 ppm NO3, 1.4 ppm PO4, 18 ppm K, 1.4 ppm Mg, 0.14 ppm Fe(TE).

High light
PPS-Pro Solution #1, 2ml per 10 gallon or 40 L
PPS-Pro Solution #2, 4 drops per 10 gallon or 40 L
Water change 50% once a week
This limits water column nutrient levels to 28 ppm NO3, 2.8 ppm PO4, 36 ppm K, 2.8 ppm Mg, 0.28 ppm Fe(TE).
(1 ml = 20 drops)

    Hi Jeff,

    For questions regarding PPS, please refer to it’s creator at https://sites.google.com/site/aquaticplantfertilizer/home/pps-pro.

    In our opinion, there is nothing wrong with the new or old recipe, just use the one that works best for your tank. thank you

  2. gla

    Yes it’s ok.

    Leaves turning brown could be the result of many things, light,co2,nutrients or any other chemical added to the tank.

    In general, nutrients addition is the easiest thing to do. Most overlook co2 and light. These 2 are harder to dial in as they are invisible elements you can’t measure or see with the eye. Because people can’t see it they think it’s not a problem. As the old saying goes, ” Out of sight out of mind”

    Nutrient addition is as easy, so plant issues such as deficiency are easily avoided. Adjusting your dose might help, likely not though.

    I’d look into your co2 and light intensity. Perhaps consider other chemicals as well, namely Seachem Excel. It’s a very harsh carcinogen that is capable of burning and melting plants. It’s pretty toxic, being mainly used as an industrial disinfectant in the medical field.

  3. Jeff Wooldridge

    Why did the trace elements dosing lower. I just ordered the pps pro

  4. Allan

    I’ve been dosing before leaving for work in the morning which is around 5:30 am.
    My lights come on around 4:30pm when I’m not home from work. Is this ok?
    Also, since I’ve started dosing I’ve noticed that the tips of older growth on some of my Broadleaf Temple plants are turning brown. Is this normal? Sort of a “it gets worse before it gets better” thing?? Thanks in advance.

  5. mike

    how often do you recommend water changes/?

  6. gla

    Store in a cool dark location. Micro solutions prefer to not be exposed to to much UV light.

  7. C hris

    What is the best way to store nutrient after its been mixed for usage? In the dark, in the fridge, anywhere? How long is each mix good for?

  8. gla

    Nitrate levels are dependent on the actual uptake demand. So if the demand for nitrate is high then simply having any registered amount of nitrate be it 5ppm or 40ppm is good.

  9. bleh

    i heard in high tech aquariums 20ppm nitrate is good…

    this kit does 1ppm per dose, right?

    What are people’s thoughts?

  10. gla

    Great question. It’s no problem, just double your dose on Friday.

  11. Eric

    I regularly leave over the weekends, meaning I have an opportunity to dose Friday, but not again until Sunday evening. How do you recommend using PPS in this situation/

  12. gla

    It’s ok to dose at anytime, as long as you dont skip dosing your good to go.

  13. Dave

    My lights go on when I’m not home. Is it ok to dose 7hrs before the light cycle or should I dose halfway through it?

  14. gla

    Hi James, PPS already contains 7% iron EDTA

  15. James

    I don’t see a response samuels question.
    Do i need to dose iron if i am using the pps fertilizer ?

  16. gla

    That depends on how your tank is set up. The increase would usually be a result of nutrient demand in the tank. So you would need to figure out what your demand is. if you’re not into water parameter testing using real lab grade test kits vs hobby test kits, then start with doubling your dose. PPS-Pro dosing system is a lean dosing system, you’re only dosing enough plant food for the plants to completely use up during that days photo period. So increasing 2-5x wont hurt anything.

  17. Jake

    How much should I increase the dose if my tank is planted heavily.

  18. gla

    PPS contains iron EDTA in its micro solution.

  19. Samuel

    Do i need to dose iron if i am using the pps fertilizer ?

  20. gla

    With PPS there is no reason to reduce, this is due to the lean formula.

  21. Katarina

    I am starting with PPS method on a 22 gallon long heavily planted tank. I do not have CO2 unit on this tank. Should I reduce the recommended dose by 50% or maybe switch to one full dose every third day…your response is greatly appreciated…thank you

  22. gla

    Yes, it’s recommended to dose daily with PPS. To help prevent mold growth, take extra care during preparation to sterilize your dosing containers; also boil your water to sanitize before mixing or buy distilled water from your grocery. Enjoy your planted tank!

  23. jose

    Hey gla is it recommended to dose daily? And what can i do to prevent the mold grow inside the bottle?? Thanks

  24. gla

    Observe for mold growth in the bottles … if present, go ahead and mix a new batch. You may just want to make a fresh batch.

  25. C. Foster

    I had purchased the PPS pro over a year ago but switched to ADA dosing shortly after. SO my question is Im getting ready to switch back to the PPS and I have both the micros & macros already mixed, is there a shelf life on either of these or should I just go ahead and mix up a new batch?

  26. gla

    James – If you are using RO water, we recommend you use GH Booster. You can find it under the Fertilizer section of our site. If you need any assistance with your current order or have any questions we can help with, please contact customer care at info@greenleafaquariums.com. We would love to help! Enjoy your planted tank!

  27. James

    Thanks for the quick response I just ordered the pps-pro fert pack but I have one more question if you use all RO water in your fresh water planted aqurium is there anything else I have to add or do I just use the pps-pro fert pack?

  28. gla

    Hi James,

    Good question … we recommend following the guidelines at https://sites.google.com/site/aquaticplantfertilizer/home/pps-pro …. ‘It [PPS-Pro] is designed especially for aquascapers who want a system that is performing well, doesn’t need testing and tweaking and also works with all lights and substrates, no water changes and large water changes. Entirely 100% planted aquariums with reasonable fish load.’

  29. James

    How often should you do a water change when dosing via PPS?

  30. gla

    You could try to dose a bit extra the week prior to departure. Then, while on vacation, shorten your photo period and decrease CO2. When you get back home, do a water change and resume your regular routine. Good luck!

  31. Brandon

    I’m thinking about dosing via PPS but I’m concerned about what to while on vacation. Any recommendations?

  32. gla

    Hi Perry …

    Thanks for your great questions! No, it doesn’t matter which you dose first, micros or macros. You can dose both daily, one after the next … no need to wait between bottles. It is recommended to dose prior to lights turning on so that the nutrients are readily available for the plants to utilize when the lights turn on. Dosing at night will be fine. Enjoy your planted tank and let us know if you have any more questions we can help with.


  33. Perry

    I just purchased your pps-pro fert pack. I can’t wait to start, I just have a few questions. Does it matter if you dose micros or macros first? Can you dose right after one another or do you have to wait? Why do you have to dose before the lights come on? And can you dose anytime at night or does it have to be right before the lights come back on?
