"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."

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!
Try it for 100 days. If it doesn’t work, get a full refund. We are aquarists too and want the best for you.

"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."
PolandWell, firts of all I was a little worry about switching ferts (before APT I was using other brand with separate elements). Decided to try APT because of three main reasons: 1) Wanted decent "all in one" because of getting tired dosing separately every element. 2) APT has greater amount of phosphate than other brands I considered (my aquarium loves P). 3) Producer dosage is real, efficient dosage. Transition went great. My plants seems to be more happy with APT :) Thank you for great product!
SingaporeReally effective and simple to use!
SingaporeAs always the best fertilizers. Would love a bigger bottle size too!
SpainTired of using NPK addition once change water or add expesive products for that, H2r seems to be my best choice. Plants have grown a lot, with no algae. So I should recommend it. At least check, if you're not convinced to change your system, once. Your trial is worth.
United StatesI've tried other fertilizers without much success, however, since I've changed over to APT complete it's been an amazing change for my plants. Within a few weeks I've noticed a difference with the growth and color of my plants. This is my only fertilizer I will use, and I have been recommending it to friends and family members who have planted tanks. Thank again for this wonderful product.
APT brings out the best growth in 'low tech' tanks without CO2 injection as well.
The big difference? It takes many weeks for results to appear, as plant metabolism is ~10X slower in low CO2 environments!
Which product is right for me?
For tanks with more fish, fewer plants. For new tanks (<3 months) with aquasoil. Comprehensive nutrition without nitrates and phosphates for maximum algae control.
For tanks with more plants, fewer fish. 100% comprehensive macro, micro and trace minerals. Unique Capstone ratio unlocks richer colors and stronger growth.
For heavily planted Dutch Style tanks and users who understand EI methodology. Supremely concentrated and expertly balanced.
It is normal for tanks less than 6 months old to have various bouts of algae issues, most of which can be avoided with proper cycling prior to planting. APT cannot compensate for inadequate cycling.
It is also normal for plants to take several weeks to adapt. APT helps to speed up the process, but you still need patience. In tanks without CO2, this takes 2-3 months. Adaptation may involve shedding leaves (yes!) and / or having leaves that appear deformed. The hardest, yet most effective response is to tinker less and provide a stable tank environment for the plants to adapt. Look for improvement in NEW LEAVES, not old ones.
A mature tank can respond to better nutrition in several ways. The best (and most common) outcome is healthier NEW GROWTH. Old leaves do not rejuvenate even when conditions improve, and may even deteriorate faster, as we explain here.
In rare cases, better nutrition can seemingly trigger algae. This can happen:
(a) if there is prior accumulation of organic waste, especially on mosses and slow growers. When plants adjust to a new nutritional environment, they release proteins that serve as food for algae. The combination of accumulated organic waste + excreted proteins can be a trigger for algae.
(b) if volatile organic matter is released due to replanting or cleaning. In mature tanks, volatile organic matter builds up naturally in the substrate and hard-to-reach corners. When inadvertently released, often coincidentally with improved nutrition, algae can bloom. This can be avoided by performing thorough water change the 2Hr way after replanting / revamping the tank.
(c) if seemingly ‘OK’ plants (especially slow growers like Mosses, Bucephalandra, Crypts, Java Fern, Anubias, Alternanthera species etc.) are actually not as healthy as they appear. Plants often respond to improved tank conditions (better nutrition, or lighting, or CO2…) by accelerating the shedding of older, less healthy leaves. This attracts algae, which help in the decomposition process. Slow growers that are not healthy are especially hard to spot, as they can be in 'Zombie’ states for a long time, as we describe here.
(d) finally, if you are making a drastic change in dosing regime (e.g. very lean to something alot richer, or vice versa), this forces plants to reprogram their cells to adapt and this process almost certainly triggers algae. A gradual transition over 2-3 weeks often helps. But the longer slow-growers have adapted to a particular environment, the harder it is for them to 'switch'.
