What you will need to get started with PPS:

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

Preparing the PPS fertilizer mix in the 500mL 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:

  • GLA EDTA Micromix – 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 PPS 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 0.5 mL or 10 drops per 10 gallons or 40 litres of aquarium water. Dose daily, prior to your aquarium lights turning on. (updated 7/7/2018, previous dosing recommendation was 0.1mL or 2 drops per 10 gallons)(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 40L

PPS-Pro Solution #2, 0.25ml or 5 drops per 10 gallon or 40L

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, 0.35 ppm Fe(TE).

Medium light:

PPS-Pro Solution #1, 1ml per 10 gallon or 40L 

PPS-Pro Solution #2, 0.5ml per 10 gallon or 40L

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, 0.7 ppm Fe(TE).

High light:

PPS-Pro Solution #1, 2ml per 10 gallon or 40L

PPS-Pro Solution #2, 1ml per 10 gallon or 40L

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, 1.4 ppm Fe(TE).

(1 ml = 20 drops)

    My second kit in 3 years

    Posted by Tyler Mcgowan on 3rd Jun 2021

    This is my second kit in 2 years and should have posted a review on year one. This kit is much nicer for me than the older PPS system. The DTPA in this kit is perfect for my PH in my planted aquarium. This aquarium fertilizer will last you a very long time. I mix one batch and that last me 6 months on the left side of my tank room. If I had used conventional fertilizer methods it would cost a fortune. This is pennies to the dollar and worth every penny. Mixing is easy, if you can make Kool-Aid you can mix your own aquarium fertilizer. My tanks are all glowing with growth.

    Game changing fertilizer system.

    Posted by Steve McNash on 20th Apr 2021

    This kit not only brought my tank back to life it has kept money in my bank. Im on my second batch and this kit will make loads more! I will never by a premixed off the shelf fertilizer ever again. My plants are glowing.

    Stellar aquarium fertilizer system

    Posted by Eric Larson on 20th Mar 2021

    Switched my dosing plan from the all-in-one solutions. Those were terribly expensive and wasteful. With my single PPS kit I can make several batches lasting me several years. I did my homework and GLA's PPS with DTPA is the absolute best system you will find for a very affordable price. I got this kit with the substrate capsules they sell and my 150g tank could not be happier.

    Such a great deal

    Posted by David Shelby on 9th Feb 2021

    What a great kit this aquarium fertilizer system is on a few levels. First, the price is amazing when you compare it to anything off the shelf. You get to reuse your bottles over and over by creating more mixs with just this one kit. You dont have to toss the bottles when your done, you just keep making more. I love this fact from a pollution stand point. So much better than tossing your bottles away in the trash. Good on Green Leaf Aquariums for that. My 6 tanks love PPS-Pro dosing using this new micro DTPA/EDTA. If you pride yourself on your aquascapes then dont be foolish thinking a bottle of Tropica or similar will be better, because it will not. This system covers all the micros and macros and you get to tailor your mix should you feel the need. Fantastic! Thanks GLA for all the support, you have a customer for life.
