Q5: What are the key factors for successfully growing carpet plants?

A5: Adequate lighting, proper CO2 supplementation, nutrient-rich substrate, and regular maintenance are critical. For instance, high light levels plus nutrients tend to promote healthy growth while preventing algae from taking over.

Q6: Do carpet plants require special substrate?

A6: Yes; most of these carpets benefit from nutrient-rich substrates that supply vital nutrients to them. They are supposed to be supported by specifically designed substrates for planted aquariums.

Q7: Should I use CO2 injection for carpet plants?

A7: The simple answer is that, yes, CO2 injection has a greater potential to enhance the growth of carpet plants by promoting lush and dense growth, especially if you are facing high light levels because, in that case, the plant needs CO2 for photosynthesis.

Q8: Can I grow carpet plants in a low-tech aquarium?

A8: While it’s more challenging, it is possible to grow certain carpet plants in a low-tech setup with moderate lighting and minimal or no CO2 supplementation. Opt for plants that are known to adapt to such conditions.
