Aquarium fertilizer NPK ( Macro-Mix) 500ml

Description

Macronutrients (NPK) are those nutrients that plants need in a larger amount. Among the macronutrients, the key nutritive elements are

Nitrogen (N), Phosphorus (P) and Potassium (K)

NPK may be used alone or in conjunction with Micro Mix. Best results are obtained when both are used. Full 3x per week dosing provides enough macro nutrients for even the most demanding tanks.

Please shake bottle before use
Dosage rate for 100L Tank

For High Light Tank

Use 3 pumps for every 100L 
Repeat 3 times per week
50% weekly water change is suggested

For Low Ligh Tank .

Use 3 pumps for every 100L 
Repeat 1-2 times per week 
20-30% weekly water change is suggested

For Advanced users
3 pumps (6ml)per 100L 
will yield the following

Nitrates 7.50ppm
Phosphate 1.30ppm
Potassium 5.50ppm

 

Target Range:
Here are the nutrient target ranges in parts per million (ppm) for High Light Planted.

Nitrate (NO3) range 20-30 ppm
Phosphate (PO4) range 2-6 ppm

Potassium (K) range 15-30 ppm

**It's important to note that these are equivalent weekly doses. For example, to achieve 20-30ppm nitrate you would dose All-in-One Fertiliser  3-4x per week.**

 

Deficiency :

Nitrogen – from nitrate (NO3)

Optimal levels of nitrate (NO3): 20ppm – 30ppm NO3

Nitrogen is generally found in every aquarium in the form of ammonia, nitrite, and nitrate. It is one of the very first nutritive elements that need supplementation in the aquarium. For healthy growth of plants, it is recommended to provide enough nitrogen for the plants to absorb. It is advised to keep nitrate level 20-30 ppm in the tank. Lack of nitrogen in the water column may result in nitrogen deficiency on the plants. The first symptom of nitrogen deficiency is new leaves will get smaller and lighter colored.

 

Phosphorus – from phosphate (PO4)

Optimal levels of phosphate (PO4): 2 – 6 ppm PO4

Phosphorus is usually absorbed aquatic plants in the form of Phosphate (PO4). But for the harmful nature of phosphate, we try to keep the amount of it as low as possible in the aquarium. Generally, this element doesn’t need any supplementation.

There are multiple sources of phosphate in the aquarium such as fish food, fish waste etc. The recommended level of phosphate in the tank is 2 to 3 ppm. Though the smaller amount you have, the better.

There is a high risk of algae bloom if there is an excess amount of phosphate in your tank. Although, if you have no phosphorus at all (which is unlikely), phosphorus deficiency may appear as yellowing of the older leaves.

Medium light and low light tanks do not need additional doses of Phosphorus. But if you have a high light tank, you may need to provide phosphorus if there is a shortage

 

Potassium (K)

Optimal levels of potassium (K): 15 – 30 ppm

 Every aquatic plant needs potassium to thrive.  It is a benevolent macro nutrient which doesn’t bring any harm, even if you liberally dose it! Potassium and Nitrogen are the two macro nutrients that need dosing in planted tank.

The desired level of potassium in a tank is 15 to 20 ppm. But you won’t face any issue if your tank has a higher potassium level than that. As potassium doesn’t bring any harm, it is safe to use more than needed in the aquarium. Potassium deficiency reveals itself as yellowing of the leaf edges, small holes in the leaves, etc.
