How to dose PPS-Pro (EDTA) Aquarium Fertilizer Package in your planted aquarium

  • Learn everything you need to know about aquarium plant fertilizer, plant nutrients, optimal nutrient levels, and diy fertilizer dosing methods: Dry Fertilizer Calculator and Fertilizing Methods.
  • Before you start, you will need a digital scale (preferably with 2 decimal places) to weigh the fertilizers and place them in the 500mL bottles
  • It's recommended to sanitize your plastic bottles prior to starting

How to Prepare the PPS DIY Stock Solution

Use your digital scale to measure the dry fertilizers and place accordingly in Macros and Micros bottles (see below measurements in grams). Next, fill bottles with distilled or reverse osmosis (RO) water, up to the 500mL water level line. Screw on caps tightly and shake well. Allow solution to dissolve completely, may take 24hrs. Warm water aids in quicker dissolution.

  • GLA EDTA Micromix - 28.6 grams

How to dose PPS Macros and Micros daily in your aquarium

  • The dosing recommendations outline below are ideal for medium and high lighting aquarium conditions. For lower light aquariums, use half the recommended dose, and for very high light double the recommended dose. Occasional monitoring of NO3 levels via conductivity readings with an inexpensive and easy TDS Meter is recommended with PPS-Pro system to adjust dosing accordingly and determine need for water change.
  • For dosing the PPS system with a 50% water change once per week, review our PPS instructions for this dosing schedule based on tank lighting, otherwise follow instructions outlined below for dosing with or without occasional water change per tank needs.

Macros: daily dose of 1 mL* per 10 gallons or 40L of aquarium water. Dose daily, prior to your aquarium lights turning on, dose consistently. *(1ml = 20 drops)

Micros: daily dose of 0.5 mL or 10 drops per 10 gallons or 40L of aquarium water. Dose daily, prior to your aquarium lights turning on, dose consistently. (increase dose if pale new growth appears)

Total daily dose yields:

  • 1ppm NO3
  • 0.1ppm PO4
  • 1.33ppm K
  • 0.1ppm Mg
  • 0.05ppm TE(trace elements)

    Way better than buying premixed fertilizer.

    Was so done with buying bottles of premix they just go so quickly and fill up the landfills. At least with this system your using the bottles over and over again. You get premium grade fertilizer so dont think those premixed solution have some type of magic in them, because they dont. Just read the label and you will see yourself. This kit has all the micros and macros. You have enough fertilizer here to make over 100G of liquid fertilizer for $35! You pay they for just 1 bottle of Tropica. Nuff said.

    Awesome fertilizer system.

    Been using this a few weeks and boy my tank is loving this system. I really like the bags. They stand up so its easy to scoop your salts out when you need to mix. Mixing is simple and dosing is way more accurate with this vs a pump system. Besides my tank is loving this stuff!

    This should be the new standard for aquarium dosing.

    Last year I had quit using all in one solutions and Tropica fertilizers. Ive used all of them. I would switch up every 6 months to see if one would offer more than another. None of the All in one solutions from Tropica or NilocG including 2hr Aquarist seemed to put the levels my tank needed. Which I feel is due to my LED being high PAR. I still felt the all in ones were just getting me buy. Fast forward to today, 2 years later Im buying my second pack. I think my last pack would have lasted longer but I tested with EI dosing and did not like it. With PPS you have options. You can dose per water change or no water change. To me, this day and age is why we should all consider dosing PPS Pro. One of these kits will last 10x longer than one all in one solution. Thats because you can make many many batches of both Micros and macros. The best part? You get to tune your mixture as the tank matures. Tune? Yes, stem plants wanting less nitrate, no problem, go lean on kno3 in the mix. Watch your red plants pop! You are not going to achieve this with an All-In-One solution fertilizer. This kit is beyond economical, but produces results. And when you notice results you can fine tune your mix just to play around. PPS-Pro is where its at.

    Buy this it will save you loads!

    So happy I pulled the trigger on this. My tank is bangin with growth and my wallet is happy. I was using all in one solutions but that was getting wasteful and expensive. With this PPS kit you can make several bottles of mixture over and over. This kit is 100% complete, NPK and micros, including Iron. Dont be a sucker like I was buying premixed solutions. Buy that if your lazy and wasteful.

    Fantastic results from my plants finally!

    Couldn't be happier, extremely affordable fertilizer system that will last me over a year. Easy mixing directions and my plants were being fed. After about, 2 months my tank was blown over with growth. I now have trimming to take to my local club and to sell its incredible! This kit is paying me back already!

    First time using this and wow!

    Total newb to this type of dosing coming from bottled liquid stuff. I only chose those methods because I thought it was a long term solution, no pun intended. It ended up being to short term for my tank of 75g. I spent a lot of money and created more waste than I cared for as I’m trying to cut down. This dosing system is perfect and I know I’ll get over a years use out of only one kit. My plants are growing much better than they ever have. Even my garden outside was going better due to my tanks water changes.

    Wisest aquarium fertilizer system to use these days.

    I can make so much fertilizer with this one kit. I no longer feel guilty throwing away one use bottles any longer. My plants responds so much faster and I can tune my mixture for my needs. I love this!

    Wonderful complete dosing system.

    This system has changed the life of my tank completely. This is a very affordable kit. I feel better about mixing my own and love I can make so many batches with one kit. I will no longer dose any other way. Everybody needs to make a change for the future in baby steps to better the earth. With this dosing kit I can keep reusing the bottles over and over and over. No more just using up and tossing into the landfill. Worth every penny.

    Economical and very high quality aquarium fertilizer dosing system.

    My tank is beaming with vigor. I love the ability to fine tune certain elements for my aquascape. This kit you can make many batches of two 500ml bottles. This is one heck of a bargain and the nutrients are the best of the best. Complete micro and macro elements, including iron!

    Planted aquarium fertilizer made easy.

    4 weeks in on using PPS-Pro. This kit has already saved me money. Not only that but helps keep empty bottles out of the ocean. I ran through so much all in one fertilizer solutions it was getting ridiculous. This system has my tank growing like never before now that I have more accurate dosing and control. This system can literally make years worth of fertilizer for your tank. You get all micros and macros, nothing is missing!

    If I could give more stars I would

    This stuff is incredible. I accidentally used too much before a business trip. Reached out to customer service and they got right back to me telling me it would be fine. I came back 6 days later to plants growing out the top of my 90gal aquarium. They seriously over tripled in size. I would post pictures if I could. This has to be seen to be believed!! Best didn’t harm my fish or snails. This will be the ONLY product going in my aquarium from now on!

    I like this dosing system much better than my premixed options. This is much better because you actually know what your dosing, and exactly how much. GLA does a great job with this system. Delivery and packaging was fantastic.

    Was a little skeptical because it was my first time using dry fertilizer. But my plants Love it Awesome product!! I will definitely be ordering again

    Better Than Flourish

    You can make many MANY batches of micro and macro nutrients. This will last years for me!

    Why did I wait so long!

    I should have started using GLA PPS-Pro years ago. I was sold on buying all in one solutions for ease of use but man did that turn out to be an absolute waste of my money. This PPS-Pro kit will make you several batches of 2x 500ml micro and macro solutions. Did you even look at the price? No brainer folks, you would be foolish to use all in one solutions or a version of store bought premixed solution. You gain nothing from going that route as I have learned the hard way. My tanks look like they are on plant steroids and I took great pleasure selling my clippings to my local club. Winner winner chicken dinner!

    Worth every penny.

    I was looking for aquarium fertilizers for my new 75g tank. after going back and forth with options I decided on GLA PPS-Pro system. It arrived quickly and neatly packed. Creating the solutions took a few minutes. I was excited to start dosing so I waited a few months to post this review. Since using PPS-Pro my tank has taken off to a new level. Ive sold most of my clippings already to friends to where my tank is paying me back. What I like most about this system is its affordability and longevity. With one kit you literally make loads of liquid solutions. You can dose both on the same day or opposite days and even adjust your recipe to your tanks precise needs. Im a chemist by nature so I really enjoyed playing around with my dosage levels and watching what plants liked and did not like. The dosing bottles are a breeze to use, just squeeze and pore. They also include a pipette with each bottle for nano tanks which i found neat. I since started a desk top vase to try it out. Overall very happy PPS-Pro, you will be too.

    Saved my tank

    This package is by far the smartest dosing system you can buy and it will cost you pennies compared to buying premixed solutions. First, premixed solutions are mostly water. You end up tossing more bottles in the landfill than necessary unless you have a really good recycling program. This kit will allow you to make many batches of 500ml Micro and Macro solutions. This is a totally complete dosing system that has everything you would need. I had no idea what I was doing when I purchased this kit and after mixing my first batch I knew I would never buy premixed solutions ever again. Save your wallet and go with PPS-Pro!

    Highly recommend PPS-Pro

    Ok so I was a little unsure of myself when going this route for my tank. Previously all I have been using are all in one fertilizers. They worked ok, but I noticed some issues, a lot actually. One issue off the bat was while my plants were living, none of them were looking nearly as good as members in my local club. I used all the brands of liquid fertilizer all in one solutions. They were extremely costly, thats a huge factor. I dont think they worked nearly as well as GLA PPS-Pro system though. My plants pearl much faster in the morning instead of noon time. My colors re super vibrant and I dont notice any more pinholes in my plant leaves. Besides my plants all looking fantastic now I my wife noticed after only 5 months of using PPS-Pro I dont spend nearly as much as I did when using the premixed liquid solutions. With one kit I cam make several batches of fertilizers. Mixing is super easy and not any different than making your favorite drink. It takes me about 4 minutes to create two bottles of high quality Micro and Macro fertilizers. Im saving loads of money and spending it on plants instead. You absolutely will be thrilled with this kit. Its incredibly inexpensive and you get to reuse the bottles over and over again vs constantly buying bottles you just toss in the trash. With this kit your doing the planet a favor and your aquscape as well. Highly recommend PPS-Pro fertilizers.
