When should you plant aquarium plants?

There are a lot of benefits of planting live aquarium plants in an established tank.

1. Added filtration

Fish require a clean environment in an aquarium for their healthy growth.

Though aquarium filter helps to keep the aquarium clean, the live aquarium plants will provide an added filtration.

All the waste present in your aquarium such as fish poop, uneaten food, etc produces ammonia which is harmful to the fish in your aquarium.

But this ammonia is actually beneficial for the plants. So the plants will absorb the ammonia and use it as a fertilizer to grow in your aquarium.

2. Oxygen

Plants respire just as we do and the fish in your aquarium does.

But the difference is plants take Carbon dioxide during the day and release Oxygen.

This helps to oxygenate the tank.

But at night time this process reverses.

At night plants take Oxygen and release Carbon dioxide.

Usually, this doesn’t cause any issue in most of the aquarium unless you are planting a lot of plants in your tank.

3. Substrate health

If you are using sand substrate in your aquarium then, as the substrate is very tightly packed, there is a possibility that oxygen may not reach deep into the substrate.

If Oxygen didn’t reach any part of the substrate then anaerobic bacteria starts to form in those areas.

The anaerobic bacteria produce hydrogen sulfide gas.

Over time this gas build-up into the substrate of your aquarium.

And it can blow up anytime.

Hydrogen sulfide gas is toxic for the fish and it can even cause the death of the fish in the aquarium.

You can easily eliminate this problem by planting root feeder aquarium plants in the aquarium.

The roots of the plants will spread out deep into the substrate which will break these anaerobic bacteria pockets. So the hydrogen sulfide gas will not build up in the substrate of your tank.

Besides, some fish also like to nibble on the plants sometimes.

Benefits of planting live aquarium plants in a new tank

Along with all the benefits that I have mentioned above planting the live aquarium plants in a new tank provides you more control.

What I mean by control is that while setting up the tank you can choose the plants of your choice and you can choose the substrate of your choice for the plants. 

Overall, you can plan out your planted tank.

1. Substrate

A substrate is one of the most essential parts when it comes to growing live aquarium plants.

A substrate is especially important if you are going to plant heavy root feeder aquarium plants like Rosetta plants such as Sword plants and Stem plants in your aquarium.

As these plants absorb most of the nutrients through their roots, planting them in a nutrient-rich substrate can really 9help them grow better and faster.

You can also plant these plants in sand or gravel substrate. But then you’ll need to provide them nutrients through root tabs.

Root tabs are basically tablets of fertilizers that you can insert near the roots of the plants.

Slowly, over time, the nutrients will get released into the substrate through the root tabs. Live plants can use these nutrients for their growth.

2. Plants and placement

If you plant the live plants while setting up the aquarium, you have a lot of choices which you may not have while planting in an established tank.

This is because, in an established tank, you’ll have to choose the plants according to the fish in your tank.

Also, you have total control over the placement of the plants. And you can design your planted aquarium as you want it to look when it is grown up.

3. Nitrogen cycle

Live aquarium plants can speed up the nitrogen cycle of your aquarium.

When you plant live plants in your aquarium, some leaves of the plants will shed off. These leaves will create ammonia in the aquarium. 

The plant will absorb this ammonia. And over time beneficial bacteria will start to form in your aquarium. 

After a few weeks, anywhere between 2 to 6 weeks, your tank will have sufficient beneficial bacteria to support fish in your aquarium.

Live plants will also provide space for beneficial bacteria.
