Aquarium Plant Care: Foundations For Success
Maintaining a freshwater planted aquarium can be a rewarding and enjoyable hobby, but it requires proper care and attention to ensure the health and vitality of the plants and fish. One of the most important aspects of plant care in a freshwater aquarium is providing the right nutrients and lighting conditions. Without these essentials, plants may struggle to grow and thrive, which can lead to an unhealthy and unbalanced ecosystem. In this article, we’ll focus on some of the key factors that contribute to plant growth and health including how to choose the right substrate, lighting, fertilization along with which tools to use for regular maintenance.
Choosing the Right Substrate
When deciding which substrate to put into your aquarium there are a few basic questions that you need to consider. First, what type of plants are you interested in? If the plants are part of the rhizome category (as in, they absorb nutrients from the water and not the soil), then sand and gravel are available options since these inert substrates aren’t responsible for providing the nutrients your plants need to thrive. Common examples of rhizome plants are Java Ferns, Anubias and Bucephilandra.
If you’d like to plant root-feeders, such as various stem plant varieties and most low level carpeting plants, then you should opt for a substrate that is more nutrient-rich like aquarium soil. Of course, you could simply use root tabs to provide essential nutrients if you'd prefer to plant in sand or gravel.
Even when using plant soil, some plants will still require CO2 to thrive and using fertilizers can boost your plant growth as well.
Water Quality and Parameters
Maintaining proper water pH and hardness levels is crucial for the health of freshwater planted aquariums. The ideal pH level for most aquatic plants is between 6.5 and 7.5, while the ideal hardness level ranges from 3 to 8 dKH. It is important to note that different plant species may have varying pH and hardness preferences, so it is recommended to research specific plant requirements.
To monitor and adjust pH and hardness levels, you can use test kits and additives. pH stabilizers and buffers can be added to the water to maintain a stable pH level, while hardness can be increased with the addition of calcium and magnesium.
Choosing the Right Lighting
Lighting is another important factor in plant growth. Plants require light for photosynthesis, which is the process by which they produce energy. The type of lighting required depends on the plants being grown. Some plants require low to moderate light levels, while others require high levels of light.
When choosing lighting for a planted aquarium, it is important to consider the intensity, spectrum, and duration of the light. LED lights are a popular choice for planted aquariums, as they are energy-efficient and provide a wide range of spectrums. It is also important to ensure that the lighting is on for the appropriate amount of time each day, typically between 8-10 hours. If algae starts to form, one of the first measures to take is to back your lighting down by a couple of hours and see if the situation improves.
Temperature
The ideal temperature for most aquatic plants is between 72 and 82°F. You may need an aquarium heater and a thermometer to maintain these temperatures. Households that lack central AC or in hot climates should consider an aquarium fan or chiller to keep water temperatures from becoming too high. If your home temperature fluctuates often, you can use a temperature controller to maintain consistent water temperatures. To control heating only or cooling only, you can use a single-stage controller. If you need to control both a heating and a cooling device, you will need a dual-stage temperature controller.
Circulation
Water circulation helps to distribute nutrients and oxygen throughout the tank, while also preventing stagnant areas where debris can accumulate. Air stones or sponge filters connected to an air pump in the corner of your aquarium are always helpful to oxygenate and create surface agitation which helps avoid dead spots where algae can accumulate. For long aquarium models or river biotope setups, you may want to add a circulation pump or two to increase flow throughout the tank.
When deciding where you want to place your plants, it is important to avoid putting them directly in front of filter outlets or circulation pumps, as this can lead to damage and hinder growth.
Plant Nutrition
For freshwater planted aquariums, providing the right nutrients is crucial for plant health and growth. Some of the essential nutrients required by plants include nitrogen, phosphorus, potassium, calcium, magnesium, and iron. Nitrogen is needed for leaf growth, while phosphorus is important for root development. Potassium helps with overall plant health and disease resistance, while calcium and magnesium are necessary for strong cell walls. Iron is essential for the production of chlorophyll, which is crucial for photosynthesis.
To ensure that plants receive the necessary nutrients, it is recommended to use a complete fertilizer that contains all of these essential elements. The fertilizer should be added to the aquarium water according to the manufacturer's instructions. It is important to avoid over-fertilizing, as this can lead to algae growth and harm the fish.
CO2 Supplementation
In addition to nutrients and lighting, CO2 supplementation can also benefit plant growth. CO2 is a key component of photosynthesis, and providing additional CO2 can help plants grow faster and healthier. While setting up a CO2 system can seem intimidating, it is really much easier than you may think. There are a variety of options including easy-to-use all-in-one kits available to get you started as well as more advanced setups that can allow you to control your CO2 more accurately and feed it to multiple diffusers from a single canister.
A simple CO2 checker will help you ensure that you are maintaining those ideal CO2 levels in your aquarium. If the liquid is blue, increase the amount slightly and wait a couple hours. If it is yellow, decrease the amount and do the same. If it is green, your CO2 levels are set correctly for that tank size and plant requirements.
Maintenance and Care
To keep freshwater planted aquariums healthy and thriving, regular pruning is essential. Pruning involves removing dead or decaying plant material, trimming overgrown plants, and shaping plants to promote healthy growth. This process not only keeps the aquarium looking neat and tidy but also ensures that the plants receive enough light and nutrients.
You’ll find that there are a variety of tools available and the easiest place to start is a complete tool kit. You’ll find the flattener which allows you to move substrate around gently within your tank. Curved scissors are ideal for cutting low and flat when pruning back stem plants or even carpeted areas. Spring scissors provide an easy solution for rapid trimming of carpeted areas where shallow quick cuts are required. The straight tweezers are designed for general planting and are a must have in any aquascapers tool box while the curved tweezers provide an option for planting in harder to reach areas. Serrated tips help prevent uprooting of plants when pulling up from aquarium soil.
Before starting to prune your aquatic plants, be sure to turn off your filtration. When trimming stem plants, cut down low on the plant stock and expect that two shoots will develop from your cut areas. You can then take the top part of that plant (3-4 inches) and replant it back in that area or in a different part of your aquarium to keep that trimmed zone looking nice while the new shoots grow in. Roots from the cuttings will take over a couple of weeks and this allows you to create richer, fuller areas in your planted aquarium. Carpeted plants can be clipped allowing the cuttings to float to the surface where they can be netted out of the aquarium. Once you have pulled out any floating leaves or plants that need to be discarded, you can turn your filtration back on.
