2HR APT1 ZERO

Tackle the most demanding plants or simply enjoy the magic of everyday life in new aquariums with aquasoil and aquariums with more fish.

The easiest way to unlock the true potential of your planted aquarium.

APT1 Zero is an all-in-one product that replicates the winning formula of APT3, without nitrates and phosphates.

It provides maximum algae control in newly set up aquariums and excellent long-term performance for aquariums with more fish.

This is because the food and waste from the fish already provide phosphates and nitrates.

We recommend that all tanks start with APT 1/Zero for the first 1-3 months.
