6 Tips to Take Care of Live Plants in Aquarium (For Beginners)

Why your aquarium plants are dying and how to revive them?

As mentioned earlier, aquarium plants die usually because of some nutrient deficiency in your aquarium.

There are some common nutrient deficiencies that can cause the death of your aquarium plant.

They are as follows:

Carbon dioxide deficiency

Carbon dioxide deficiency may be the reason your aquarium plants are dying.

The symptom of CO2 deficiency is yellow leaves and cripple the growth of the plants.

In the case of CO2 deficiency, you should supplement your plants with CO2 fertilizers or pressurized CO2.

Also, you should regularly monitor the Carbon dioxide levels in your aquarium using a drop checker.

If you have a very heavily planted aquarium then the carbon dioxide level should be about 20 to 30 mg / l in your aquarium.

Nitrogen deficiency

Now nitrogen deficiency is one of the most common deficiencies that occur in the aquarium if you are just starting out with the hobby.

Nitrogen deficiency occurs when there is not a sufficient amount of nitrate in the aquarium.

The thing is, plants require nitrate for or their proper growth and if there is not sufficient amount of nitrate in the water then it can cause yellowing leaves or translucent leaves in aquarium plants.

Usually, nitrogen deficiency is caused if you are doing water changes very frequently.

Because when you do water change very frequently you are removing all the ammonia and nitrate from the water and there is not sufficient nitrate or ammonia for the plants to consume.

So, if you notice symptoms of nitrogen deficiency i.e. the leaves start yellowing and turning translucent then there are a couple of ways to increase nitrate in the aquarium.

Feed your fish

The first way is to feed your fish so they can poop and that will ultimately get converted into nitrate or ammonia which will provide nitrogen to the plants.

Use fertilizers

Another way to increase nitrogen in your aquarium is by using fertilizers.

If you are not already using fertilizers then you should start using fertilizers to increase nitrogen levels in your aquarium.

If you are already using fertilizers then you should increase its dose.

Because most of the time what happens is that the plants grow in the aquarium but the amount of fertilizers you provide to the plants is the same.

So basically you are providing less fertilizers than necessary to your aquarium plants.

In a nutshell, you should increase the fertilizer dozing with the growth of the plant.

When you introduce a new plant in your aquarium you may notice that its leaves start yellowing and fall off.

The thing is most of the plants grown in some kind of farm before you put them in your aquarium.

And when you introduce them into your aquarium, the plants actually have to adjust to the new environment.

In this process, the existing leaves of plants turn yellow and fall apart and then the new leaves start forming which are comfortable with the environment of your aquarium.

Iron deficiency

In the case of iron deficiency, the leaves of the aquarium plants start turning yellow or lime-yellow in color and its veins get darker in color.

So, to overcome iron deficiency you should supplement your aquarium with iron-rich fertilizers.

Most of the fertilizers contain iron in a very low amount. So in case of iron deficiency, you should provide complete iron fertilizers to your aquarium plants.

Potassium deficiency

Potassium is one of the essential nutrient for plant growth and development.

It is very easy to identify potassium deficiency.

You will see small pinholes on the leaves of your aquarium plant in case of potassium deficiency.

To cope with this deficiency, you should supplement your aquarium plants with fertilizers containing potassium.

Phosphate deficiency

If you notice the leaves of your aquarium plants are turning yellow and there are some brown patches and a big hole in the leaf then it is a symptom of phosphate deficiency.

In the case of phosphorus deficiency, you should supplement your aquarium plants with fertilizers containing phosphate.

Magnesium deficiency

In the case of magnesium deficiency, the leaves of your aquarium plant will fade in color.

They will get light green and the veins of the leaves will be dark green.

So, in case of magnesium deficiency, you should supplement your aquarium plants with fertilizers containing magnesium.

Calcium deficiency

If you noticed that new leaves of your aquarium plants are relatively short and light green or lime green in color then it is a sign of calcium deficiency.

This deficiency is very rare because if you are using tap water in your aquarium then chances are it contains calcium.

In the case of calcium deficiency, you should supplement for aquarium plants with fertilizers containing calcium.

So, as you can see, the solution for most of the deficiencies is providing fertilizers to your plants.

Or if you are already supplementing fertilizers then you should increase its dose.

While supplementing fertilizers make sure that it does contain the macronutrient or micronutrient which lacks in your aquarium.

For example, if you noticed an iron deficiency in your aquarium then you should supplement the fertilizer that actually contains iron in good amount or you can use complete iron fertilizers.

After supplementing your plants with fertilizers you should wait for 2-3 weeks to notice any improvement.
