High-Energy Root Capsules for Demanding Aquarium Plants
2Hr Aquarist APT Jazz are advanced root fertiliser capsules for planted tanks.
They recharge depleted aquasoil, deliver concentrated nutrients directly to the roots and make
nitrate-limitation setups much easier to run.
What Makes APT Jazz Different
- Powerful root fertiliser for thicker, fuller plant growth
- Designed for demanding root feeders like Echinodorus, Cryptocoryne and many stem plants
- Rejuvenates mature / exhausted aquasoil without resetting the tank
- Supports deep reds in plants when combined with low water-column nitrates
- Formulated specifically for aquariums – no “garden osmocote” surprises
Phoenix Matrix & Nitrate Limitation
At the heart of APT Jazz is a specialised nutrient matrix that binds
ammoniacal nitrogen and essential macros and micros within the substrate. This keeps
nutrients where the roots need them, instead of leaking into the water and breaking
nitrate limitation. The result: healthier plants, stronger colours and better algae control.
How to Use
- Insert capsules directly under the root zone, at least 3 cm / 1.2" deep
- Use roughly 1 capsule per 4 × 4 cm plant area or similar planting density
- Replenish about every 2 months, depending on plant mass and growth
- Always siphon away stirred-up detritus after planting or adding capsules
When APT Jazz Shines
- Established aquariums with mature or depleted aquasoil
- Heavy root-feeding plants that have slowed down or lost colour
- Layouts aiming for intense reds through nitrate limitation
- Aquascapes where you want strong growth without boosting water-column nutrients too much
Ingredients & Nature of the Product
APT Jazz consists of clay-based root capsules infused with inorganic macro and micronutrients
(NPK with magnesium and trace elements such as iron, boron, copper, manganese, molybdenum and zinc).
Nutrients are slowly released around the roots over several weeks, providing a stable, long-lasting feed.
