Product details

Aquarium fertilizer NPK ( Macro-Mix) 500ml


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.

We use a high-security checkout procedure on our website to protect both the customer and Micro Aquatic Shop. This extends our processing time to 3 days as we fully verify our customers and fulfill orders.


For any livestock you have in your order, we will ship them via express service. This will usually take from 1-3 days to reach you. (after leaving our workshop)

Any other dry goods, bonsai, plants, and accessories, we will send via normal post. Usually, you will receive the items within 3-7 business day (after leaving our workshop)

Note: Most often, we will deliver the orders we packed during the day to the local courier, and they will be on the way to you.

How we pack our livestock:

When having fish shipped to you, it is important to plan accordingly so that your fish arrive in good health and with as little stress (to them) as possible. Unlike receiving a regular parcel, some extra care and planning must be taken to ensure the safe arrival of your fish.

This is how we pack our fishes/shrimps/snails:

Our livestock will be carefully selected and caught out and bagged with plenty of water and oxygen,

*For shrimps, we will put a bit of plastic net mesh in to grab on so they can stay relaxed and secure in their journey to the new home.

We then wrap bubble wrap around the fish bag and will carefully place it in a Foam Box. *Foam boxes are great to create a stable environment and temperature for the livestock when shipping, and they are also very durable. We then slid the foam box into a parcel bag then sealed it with a lot of fragile stickers around it.

Shipping Schedule  in our current Sydney Workshop:

  • Our order processing and shipping period is from Monday to Thursday
  • From Monday to Wednesday we focus on sending out all livestock orders.
  • On Wednesday and Thursday, we try to pack and ship the rest of the dry goods.

Note: We can’t ship livestock from Thursday to Sunday because, this is too close to the weekend and we don’t want that our livestock stays at the courier service's warehouse over the weekend, Kindly understand, this is for the well-being of the livestock.

*All shipping times exclude courier delays.


Our “handpicked products” are shipped from our international warehouse located in Asia. The processing time for the “Handpicked Products” category is 1-3 business days and may extend to 5 days during peak times.

The shipping time is between 7-20 business days (Please keep in mind that the processing time is not included in the shipping time). Orders are not shipped or delivered on weekends or holidays.
