HOW IS APT DIFFERENT?
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?
Healthy plants, happy fish, algae-free.
I’M HAPPY WITH MY EXISTING FERT!
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?
+ 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!
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.
