Dosage Guide for APT 1 ("APT Zero") and APT 3 ("APT Complete")

APT Dosage

Total Dose in 1 week: this is the important target. It is the cumulative total amount that you should dose in one week. Plants do better with more uniform access to nutrients, so achieve this weekly target by dosing daily or a few times a week. Precision is less important than consistency.  


How is APT different?

Real results.
Plants grown the 2Hr WayTM using APT display a unique richness and form.
We developed APT because we could not find any existing product that met our needs.

I don’t need such power?

Even for the simplest tank, good plant health helps prevent algae and keep fish happy.
APT ensures your plants get 100% of what they need.
Healthy plants, happy fish, algae-free.

I’m happy with my existing fert!

Sure thing!
As aquarists ourselves, we say ‘whatever works’.
The right performance fuel just makes it easier and (we find) a lot more exciting.

Really 3X Savings?

APT Complete contains the 3 macro nutrients Nitrogen(N), Phosphorus(P), Potassium(K) + Iron(Fe)
+ Essential Trace Minerals. Importantly, in the right amounts.
You can buy these 5 individual components (e.g. Potassium) for around US$15 each.
5 x $15 = $75.

Too good to be true!

We are the first to say that a super fert by itself cannot deliver a dream tank.
Good flow, bio-filtration, the right plant mix, water parameters etc. all matter.
That is why we pair it with the internet's most comprehensive resource on planted tanks, right here.
