FAQs and Additional Tips
Can Aquarium Plants Live without Substrate?
Yes, you can grow aquarium plants without substrate as it is not necessary for all live plants. While some aquatic plants need a substrate form, which could be gravel, soil, or sand to anchor the roots to the surface, others do not.
You can keep these aquarium plants alive by attaching them to ornaments in your tanks, such as rock or driftwood, before putting them in your aquarium. Examples of these are Riccia fluitans and Java moss.
Another category of aquarium plants that don’t need substrate is floating plants. You don’t need to anchor them to anything. You may place them in your aquarium, so they float. They will do just fine and get all the necessary nutrients from the water through their leaves and roots. However, you might need to supplement these plants with some liquid fertilizers. Examples of these plants are Duckweed and Rotala Indica.
How Can You Plant Aquarium Plants in Sand?
The key to making sure your aquarium plants stay in the sand is to have enough space to grow. You should make sure that the sand substrate should be 2 – 3 inches deep at the minimum.
This should be enough to give the plants support and space to fix their roots. If you have fishes or crayfish species in your tank that can uproot the plant’s root from the sand substrate, you might have to make the sand substrate deeper.
Thicker substrates have more anaerobic areas, and heterotrophic bacteria will naturally form in these places, usually in the lower level of the substrate. This bacterium creates Hydrogen Sulphide pockets which could kill the shrimp and fishes in your tank. Oxygen is the best way to neutralize the hydrogen sulfide and return it to its non-toxic sulfate form.
Sometimes plants may float in the tank as sand may not give the perfect hold. Use lead weights to keep the plant roots in the substrate for good anchorage. Also, make sure the plant’s crown isn’t buried so the plant will not rot and remove debris on top of the sand during regular maintenance. Anytime you change the water, do so carefully so as not to dislodge the sand bed.
Is Sand Safe for Aquariums?
Sand is safe for aquariums and is one of the popular choices for aquarium substrate. They come in various forms, colors, and shades, with some being fine and others being almost as coarse as gravel.
Gravel or Sand Substrate: Which is Better?
Choosing between the above substrates will depend on the fishes and plants in your tank and personal preference. Here are the details to consider before choosing gravel or sand
Tidy looking appearance
Canister or Hanging filter
Prefer an easily maintained environment
Willing to take on the challenges of maintaining a sandy environment
Not decided which aquatic species to put in the tank
Intend to keep freshwater fish or invertebrates that borrow in the substrate
Want a wide variety of substrate colors and sizes
Not bothered about limitations of growing aquatic plants
All of the above plants will perform great in a sand substrate, and we could easily recommend anyone to you based on your needs and conditions.
However, if we recommend only one from this list, it would be Anubias as it ticks all the boxes. It is a hardy plant that can easily adapt to water conditions and requires only minimal care.
Another great option is Anacharis if you have a freshwater tank.
As long as you keep an eye on your plants and keep to the general conditions they need for survival, you shouldn’t encounter any issues with these plants.
