Can I Plant Aquarium Plants Straight into Gravel?
The precise answer is YES. You can plant aquarium plants straight into gravel for both established and new tanks. All you need is a rubber or other suitable material that will help keep the plant attached to the rock.
Gravels allow water to flow through them. So, it helps them get enough water and nutrient supply required for their growth. It is best for plants with no true roots and those that can get nutrients with their leaves.
Do Aquarium Plants Grow Better in Sand or Gravel?
Both sand and gravel work perfectly for aquarium plants, depending on the nature of each plant. Sand works better for burrowing plant species. It suspends the plant’s roots, supplies nutrients, and provides support.
Gravel works best for plants that lack true roots and need to attach. Gravel is also an excellent choice for plants that get nutrients from plants. It allows water to flow through to ensure a proper supply of nutrients and water.
Can You Grow Carpet Plants in Gravel?
Of course, you can grow carpet plants in gravel, depending on the size. It makes it easy for the plants to attach and spread over the surface. Gravels also allow each stem to cling with ease to provide more support.
Can You Mix Gravel and Sand in An Aquarium?
Of course, you can use sand and gravel together in an aquarium. But it would be best if you kept some things in mind before going ahead with such plans. First off, regardless of how you place them, the sand will settle at the bottom while the gravel moves upwards.
Note that it would be a bad idea to use sand with gravel when you have an under-gravel filter. The sand can block the vital process of the filter, therefore causing problems in the tank.
Gravel and sand are two impressive substrates in a fish tank. They support the growth of various plants. It is best only to use plants that will thrive on the substrates in your tank.
The list above contains suitable plants that can grow on gravel or sands. Also, ensure you consider your tank needs when choosing the best plant for your tank. The plant’s choice will help you to figure out the best substrate.
