With the 2HR Aquarist APT-EI, the famous nutrient dosing approach pioneered by Tom Barr is now available in a ready-to-use concentrate that removes the guesswork from trying to recreate this powerful and sometimes elusive formula.
Buying the nutrients separately easily add up to US$75+. A 500ml bottle of APT costs US$24.99
"I have a nice 135 gallon planted tank. The plants were nice, they grew ever so slowly and appeared healthy yet the color was not great. Corn white leafs and some paleness to the general look. I was using both in gravel ferts and bi-weekly doses of seachem products. I ordered the 2hr Aquarist fertilizer. in three days ( one dose) I thought I noticed some greening up of the riccia. In one week and two doses it was obvious that the ground cover ( Cuba) and the riccia were definitely greener. Two weeks on and the planted aquarium has taken on a whole new green green, healthy look! GREAT product."
100% comprehensive Macro+ Micro formula of N, P, K, Iron and Traces in our proprietary Capstone RatioTM.
APT has been an absolute joy to use! My plants have experienced significant growth and colouration when paired with CO2 injection. What is best is that the product contains all the macro, micro and trace elements all in one! The dosing regime is also really simple and convenient, perfect for me even with my tight schedule. It saves me the time of mixing my own nutrients and saves me the money of getting all these nutrients separately. Thank you for making such a great product right here in Singapore!

"Firstly I'm a beginner aquascaper. In my very short aquascaping life I used many fertilizers like ADA, EI, APK and APT. But most of all I like APT most. Because it's cost effective [and] so amazing. You can see changes within 2 weeks. Also I'm a lazy man [so] it is most suitable...for me 'cause l need to change water once in two weeks? Now my plants are more bright and healthy. I recommend to you that you need to sharp[en] your scissors 'cause you need to trim more and more after you use APT. Thanks 2Hr Aquarist for APT."
This product has worked extremely well for me. All my plants are very vibrant in color and have been growing like crazy. All my greens pop out as well as my reds. The one thing that you should know is there is no pump attachment available in the US, so you will need to purchase something on Amazon, but Don (2Hr Aquarist Team member) has told me they are working on something as well as the costumer service is like no other, there is so much information on there blogs and they want you to succeed and help you out when you need it. 10/10 for the whole 2Hr Aquarist product and team. Definitely recommend for anyone who’s thinking about this.
The plants look healthy and Fast growth No livestock lose Suitable with dutchstyle and Farm tank.
I’ve had excellent luck growing my mini hair grass carpet with this fertilizer. I have a high energy system (60 PAR, 30 ppm CO2, 7.5 ppm O2) so I have been dosing 5x the recommended amount of fertilizer daily to ensure there are no nutrient deficiencies in the tank (and to stop any feast/famine cycle). I combine this with a 50% weekly water change. All of these steps follow George Farmer’s recommendations for a high plant growth with the EI method.

We also have a detailed FAQ here that may help.
The short answer is that you should start dosing water column fertilizers as soon as you have plants in the new tank and no later.
New plants have no established root system, which limits their ability to draw nutrients from the soil.
