Which product is right for me?
APT 1 is perfect for tanks with more fish, fewer plants. Also for new tanks (<3 months) with aquasoil. Enjoy comprehensive nutrition without nitrates and phosphates for maximum algae control.
APT 3 is perfect for tanks with more plants, fewer fish. Enjoy 100% comprehensive macro, micro and trace minerals. Unlocks the full potential of the hobby's most demanding plants.
APT e is perfect 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'.

Conventional aquarium fertilisers were developed decades ago for fish tanks that kept mostly fish. APT is designed based on the latest developments in plant hybrids, lighting and fertilisation science.
APT's all-in-one solutions provide the macro nutrients Nitrogen(N), Phosphorus(P), Potassium(K) + Iron(Fe), Magnesium & Essential Trace Minerals. Importantly, in the optimal form and amounts.
Each individual component (e.g. Potassium)easily costs US$18 each. Even dry-fert users choose APT because of the smart savings.
With APT, you access a success-system used by thousands of aquarists across 20+ countries. Richer colors, better growth, less algae. Unlike other fertilisers, APT comes with a fully integrated methodology that makes the journey far more enjoyable and rewarding.
GreeceI have been using APT Complete for about 18 months in my tank, planted with a mixture of stem plants and slower growing plants. Along with a proper maintenance and CO2 injection APT Complete has proven to be a good tool to achieve healthy plant growth, good colour and a steady manageable growth rate by dosing the reccomended amount. Shipping to Greece was fast and problem free.
SingaporeTesting- able to send review?
United KingdomHave used numerous brands, all recommended by numerous aquascapers, always ended up with difficulty being able to balance the tank and ended up with algae. Have just gone through my first bottle of 2Hr Aquarist Complete and plants are growing perfect, literally have zero algae and I used the exact dosage recommended on the FAQ’s. 10/10
United StatesI’m using APT Complete in 2 tanks where both had algae and plants that were struggling. Now the algae is gone and the plants are doing well. I literally changed nothing else - just added a few squirts each day to the 55 gallon and one a day to the smaller tank. Very happy!
