Buyer’s Guide: Choosing the Best Aquarium Carpet Plants & Grasses
Let’s look at some important things to consider before you purchase your next aquarium carpet plant.
Propagation refers to how fast the plant spreads. Some plants spread on their own through runners that branch off the parent plant and sprout new ones. However, most others will require you to prune the plant with long sharp scissors and planting the cuttings. You can prune faster-growing plants more often, and it will be easier to create a complete ground covering. However, if you are looking for an accenting plant, you will want something slower growing.
The next thing you will want to think about when choosing a carpet plant for your aquarium is how tall the plant will be when fully grown. Shorter plants are perfect for the tank’s front and are great for attaching to driftwood and other items in the tank. Keep your foreground plants under 4 inches.
Plants taller than four inches are best suited to the back of the tank, where they will not obstruct your view. These plants are attractive and provide a fantastic hiding place for shy fish and for those that are breeding.
Many plants will not require additional lighting but some will. With the increasing popularity of LED systems replacing the traditional bulb that requires plenty of electricity and frequent changes, adding more light to your aquarium is inexpensive and long-lasting. These LED systems can provide your plants with the full spectrum of light your plants require to grow.
Many plants will require carbon dioxide for optimal growth. Even those that don’t need it will benefit from adding it to the tank and will often grow faster and taller. However, adding CO2 to the tank requires an entire system, and the knowledge to use it. In most cases, you can buy the whole kit online or from a pet store. You will need a tank of gas, a CO2 regulator, a bubble counter, and tubing. Often purchasing the whole kit will supply you with the instructions for installing it.
All of the plants we chose to include on this list are easy to maintain and require little effort to keep them alive. However, many other varieties are much more challenging. If you are inexperienced, we highly recommend choosing one or two of these varieties first to gain the experience you need.
