Provides a powerful visible growth boost, even to the most demanding plants.

Unparalleled Nitrate Limitation ability unlocks the deepest possible reds in popular plants.

Nitrate Limitation

Nitrate Limitation unlocks the deepest possible reds in Rotala rotundifolia and many of the hobby's most popular plants.

This technique involves root-fed macro nutrients, coupled with low nitrates in the water. Existing root tabs either do not contain sufficient root-fed macro nutrients, or do not effectively retain nitrogen within the substrate. Once leeched into the water, nitrate limitation fails.

APT Jazz was specially engineered to retain potent ammoniacal nitrogen within the root zone. Enjoy the power.

Visible Boost

APT Jazz was engineered to give fuller growth forms and stronger growth, even to the hobby's most demanding plants.

A boost that endures over 2 months. Conventional root tabs derived from terrestrial osmocote type fertilisers typically provide a quick boost for the first 2-3 weeks.

In addition, some terrestrial 'osmocote' fertilisers damage aquarium substrate over time as the contents of trace minerals used in terrestrial agriculture is often unsuitable for closed aquarium environments.

Less surprises

Many aquatic root tabs are derived from terrestrial 'osmocote' type fertilisers. They can be strong growth boosters, but often induce dangerous spikes in ammonia, which trigger algae and can kill fish and plants. Tissue-culture plants are especially vulnerable.

APT Jazz is 100% designed for aquatic use, with no unpleasant suprises.
