DMYAX Potassium Plus 300ml is formulated to provide a reliable, easy‑to‑dose source of potassium for freshwater planted tanks.

Why Potassium Matters – and How DMYAX Potassium Plus 300ml Helps

Potassium plays several important roles in aquatic plants:

Supports strong, vigorous growth and healthy cell function
Helps regulate water balance within plant tissues
Contributes to leaf colour and resilience
Works together with other nutrients for balanced growth

When potassium is lacking, plants can’t use other nutrients efficiently, even if they’re present in the water. DMYAX Potassium Plus 300ml ensures this crucial macro element is always available, helping plants stay robust and actively growing.

Recognising Potassium Deficiency

DMYAX Potassium Plus 300ml is especially useful when you see classic signs of low potassium, such as:

Chlorosis (yellowing) of older leaves
Necrosis (browning or dead patches) on leaves
Pinholes forming in leaf blades
Weak stems and roots and generally poor growth

Regular dosing of DMYAX Potassium Plus 300ml helps correct and prevent these issues, allowing new leaves to emerge healthier and more vibrant.

Dosing Instructions for DMYAX Potassium Plus 300ml

Use DMYAX Potassium Plus 300ml as follows:

Add 10ml (1 capful) per 60L of aquarium water
This dose raises potassium by approximately 2 mg/L

For best results:

Pre‑mix the dose with a little aquarium water before adding it directly to the tank
Dose 2–3 times per week, or adjust as needed based on plant growth and visible signs of deficiency
Monitor plant response over a few weeks and fine‑tune your schedule accordingly

Always shake well before use.

Integrating DMYAX Potassium Plus 300ml into Your Fertiliser Routine

DMYAX Potassium Plus 300ml can be used:

Alongside comprehensive liquid fertilisers that may be lower in potassium
In high‑light or CO₂‑injected tanks where plants consume nutrients quickly
In low‑tech setups where you still want to avoid potassium shortages

By pairing DMYAX Potassium Plus 300ml with a good all‑round fertiliser and, if used, a carbon source like liquid carbon or CO₂, you give your plants everything they need for dense, healthy growth.

Ideal for a Wide Range of Planted Aquariums

Whether you keep a simple planted community tank or a more advanced aquascape, DMYAX Potassium Plus 300ml is a valuable tool to:

Maintain consistent potassium levels
Prevent common leaf problems linked to deficiency
Support strong roots, sturdy stems and rich green foliage

Used regularly, DMYAX Potassium Plus 300ml helps keep your plants in top condition and your aquascape looking its best.
