Q & A

 

Can aquarium plants survive under natural sunlight?

In fact, if the tank is near a sunny window it needs artificial light too but not too much maybe just for 5 hours a day.if the tank is in direct sunlight this will cause algae problems. You will notice rapid algae growth inside your tank and you will have no solution to get rid of them. So try to find a place for your tank where the sunlight never reaches directly.

 

Can aquarium plants survive without sunlight?

Yes, it can unless you don’t use LED or any artificial light for 10 to 12 hours a day. So if you can’t provide these hours to your tank then you will need to put your tank in a place where the sunlight can reach but not directly.

 

How much light do low-light aquarium plants need?

If you use sunlight with artificial light for 5 hours a day it will be perfect but if you don’t count on the sunlight you can increase the light for 8 hours a day. The duration can vary depending on the brightness power of your light. Pair in mind that too much light can cause excessive algae growth.

 

How many hours a day should the Aquarium light be on?

The common hours are 8 to 10 hours a day if you don’t count on the sunlight. But if the brightness of your LED is too high in this case try to stick with the minimum which is 8 hours a day.

 

Can aquarium plants grow in gravel?

Yes, you can grow plants in gravel, but you need safe pond rocks and rubber. To plant, attach your plant to the fish safe rock using a rubber band above the roots. This will weigh down the plant once you place it in the fish tank and also keep the roots under the gravel. But this doesn’t suit all plants. Like any living thing, plants require specific conditions to grow up, and the kind of substrate where you embed the roots is one of them. The best gravel size is 3-8 mm thick because larger gravel will block root growth and smaller gravel could damage the fragile roots, and mix the gravel with the substrate.
