Besides light and carbon dioxide, Nitrogen is the most needed element by aquatic plants to grow healthy. After carbon, this is the element plants need the most amounts. A nitrogen deficiency results in slower growth of aquatic plants, which is also the reason for algae growth.

Why plants need nitrogen?

Plants require nitrogen for hundreds of things. As an example, all amino acids have nitrogen in them. Amino acids are the building blocks of proteins, without which no life can sustain. Nitrogen is also an important part of chlorophyll, nucleic acid and plant hormones.

The air we breathe has 78% Nitrogen in the gaseous form, but plants are unable to use it in the gaseous form. The most usable state of nitrogen for aquatic plants is ammonium (NH4) and Nitrate (NO3). Some plants can also absorb nitrogen that is in the form of urea (CH4N20). The nitrogen cycle is very important for both terrestrial and aquatic plants. This cycle explains the conversion of ammonia, nitrate, nitrite, ammonium, urea to gaseous nitrogen, which is performed by a bacterial colony.
Sources of Nitrogen in an aquarium:

In the aquarium, leftover fish food, various organic compounds, fish waste, etc. degrades and produces ammonium. A good bacterial colony will convert it to nitrate by this process: Ammonium àNitrite à Nitrate. This organic source of nitrogen can often be insufficient for a heavily planted tank.
How plants use nitrogen?

Some species of aquatic plants prefer nitrogen in the ammonium form, while some other species prefer it in nitrate form. Some plants even use both of these forms. It takes a lot of energy to convert nitrate into ammonium, however, vacuoles in the cell of the plants can store nitrate ions and they have high transportation speed within the plants. Unlike nitrate, ammonium is never stored within the plants. They are used right away or converted to nitrate by a bacterial colony. If the pH of the water becomes more than 7.5, ammonium can turn into ammonia, which is poisonous and also the reason for high algae growth. High level of nitrate forms inorganic sources such as Potassium Nitrate 
(KNO3), which is not poisonous for many organisms in the planted tank.
Nitrogen Deficiency Symptoms:

=>Plants turn to yellowish color. The older leaves become more yellowish than the younger ones, though the older leaves do not die.

=>Smaller leaves becoming lighter in color is also an indicator for nitrogen deficiency.

=>Nitrogen deficiency also results in a very slow growth rate of aquatic plants.

=> Some species of plants may show a reddish discoloration.

  • Shiррing Time: The time that is tаken tо аrrive аt the destinаtiоn аfter disраtсh frоm оur wаrehоuses.

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.
