Definition of Aquarium Plant Fertilizer
Aquarium plant fertilizer is also referred to as plant foods that contain micro and macronutrients. Inside the tank, live aquariums plants need fertilizers to successfully thrive. The aquarium plant fertilizer is generally found as a substrate or liquid form. In this case, the substrate forms typically stay a longer period of time in the tank while the liquid form needs to be dosed periodically. To encourage aquarium plant growth in moderate to heavily planted fish tanks, you must use aquarium plant fertilizers which are readily available in the aquarium pet fish market.
In the aquarium pet fish market, the fertilizers come with the essential nutrients that enhance the proper growth of your aquatic plants. In this case, calcium helps to aid in imparting the plant’s colors that greatly maintain fresher-looking and greener plants inside the tank. In the market, various forms of fertilizers are found which play a substantial job for maintaining a well balanced and fascinating fish tank growth.
Essential Nutrients for Aquarium Plant Fertilizers
Essential nutrients must be included in the plant fertilizers which should be broadly divided into two: macronutrients and micronutrients. In this case, macronutrients like Nitrogen (N), phosphate (P) and potassium (K) are undoubtedly the most valuable nutrients that plants use in large quantities while micronutrients are often needed in very small amounts. Other essential macronutrients are sulfur (S), magnesium (Mg) and calcium (Ca). These nutrients along with light and water play a key role in the plant`s survival.
The aquarium water, fish food, and fish waste also contain some macronutrients. The aquarium water contains nitrogen with three different forms: ammonia, nitrite, and nitrate. If the tank contains high levels of nitrogen, the water is harmful to the aquarium fish population. Fish waste produces ammonia which can be converted to nitrite and nitrate by the action of beneficial bacteria.
Plants use different nitrogen forms and reduce the nitrogen level in the water. If the tank contains a large number of plants, the nitrogen level can decrease very quickly. In the aquarium water, the suitable level of nitrite is 0.2mg/ml while the nitrate level is 25ppm. In this case, you should regularly maintain the nitrite and nitrate levels. With a lack of nitrogen, it is recommended to add the nitrogen in the aquarium water while with an excessive amount of nitrogen; the aquarium water should be partially changed.
Plants get some essential macronutrients from the habitat soil while other nutrients receive from the supplied fertilizers. The most important macronutrients are Nitrogen, phosphorus and potassium (NPK) which are also called the fertilizer elements. They have multiple roles to a plant`s survival. In this case, nitrogen is a part of proteins and nucleic acids which is used for synthesizing vitamins. Besides nitrogen also enhance the strong leaf growth. Phosphorus helps to encourage budding and flowering while potassium influences the root growth.
Phosphorus is an important element that is essential for the health of the plant. Plants get phosphorus from fish food and fish waste but if your tanks have a high lighting system, you should use additional phosphorus. You should always check the water to maintain a suitable phosphorous level before adding phosphorous into the tank because excessive phosphorus can be harmful to the fish and it also enhances the algae growth which causes algal bloom.
For strong growth with healthy plants, potassium plays an important role. Potassium is essential for plant growth; strengthen their roots, and leaves. It also helps to regulate a healthy water balance by opening and closing of stomata of leaves. You should supply it as a supplement because fish food and waste do not contain sufficient potassium. You can purchase it from the online shop at a reasonable price.
The most common micronutrients for aquarium plants:
- Iron (Fe)
- Manganese (Mn)
- Chlorine (Cl)
- Copper (Cu)
- Boron (B)
- Molybdenum (Mo)
- Cobalt (Co)
- Nickel (Ni)
Different Types of Aquarium Plant Fertilizers
In the aquarium fish market, there are following types of aquarium plant fertilizer:
Substrate fertilizer is a vital element for well-planted tanks or aquascapes because it is needed for healthy plant growth. If you use substrate fertilizers then you have to reduce the considerable amount of fertilizer that you add to the water column. Some plants receive nutrients through their root systems; they are referred to as heavy root feeders. In the pet fish shop, substrate fertilizer is found in the powder form that contains laterite. For proper growth of the plant root, laterite should be placed in the deepest layer of the gravel which supplies iron to the plants` root. These foods contain the ingredients especially suitable for root-feeding plants such as Amazon Sword, Dwarf Baby Tears, Cryptocoryne, Echinodorus, Glossostigma, Cobra grass, Dwarf Hair Grass, Sagittaria, Vallisneria, etc.
When you use substrate fertilizer, it should be mixed with the lower layer thoroughly to prevent increasing the iron level in the water. Otherwise, it can cause algal blooms. If your tank does not contain root feeding plants, then you should not use this type of fertilizer.
Aquarium Fertilizer Root Tabs
Aquarium fertilizer is also available in tablet and stick form. Actually, they are tiny pieces of compressed plant foods. If your tank contains inert substrate such as gravel or sand, you can easily use it. In this case, you have to carefully bury the tab into the gravel in a sphere surrounding the plants. After that, the tabs gradually dissolve and the rooted plants consume the nutrients. In many cases, it contains a high level of nitrogen with a low level of phosphorous which is suitable for aquarium plant growth. These substrate fertilizers can control algal growth because they cannot reach to the nutrients in the substrates.
Liquid Aquarium Fertilizer
Liquid fertilizer is also found in the pet fish market which is more suitable for rootless plants. When you add this fertilizer into the fish tank, it is generally dissolved in water and the plants absorb nutrients through the water column. Floating and rootless plants receive this fertilizer for better growth and nourishment because this type of fertilizer provides all the necessary micronutrients. You can use it daily or weekly basis for the proper growth of plants.
This fertilizer is suitable for Java Fern, Anubias, Brazilian Pennywort, African Water Fern, and Mosses that feed directly from the water column through their leaves and stems. If you use liquid fertilizers in combination with substrate fertilizers, aquarium plants will grow stunningly, making a magnificent Nature Aquarium aquascape.
It is recommended to use the proper amount of micronutrients and macronutrients because excessive use of these can cause algae problems. To prevent the deposit of the fertilizer in the tank you should change partial tank water at regular intervals. If you have planted tank with fast-growing plants, you should use high amounts of microelements in the water. In this case, you should purchase a plant fertilizer that contains iron, manganese, zinc, boron, magnesium sulfur, and copper.
Benefits of Aquarium Fertilizers
Best Time to Fertilize For Aquarium Plants
Feeding your aquatic plants should be done at the appropriate time. It should be done in the morning because plants need more nutrients for performing photosynthesis throughout the day. Each day or every three, four or so days, the ideal time is within an hour interval after the lights are turned on. Generally, grass-like plants take 15-24 hours to absorb nitrogen fertilizers into its leaves.
To make the aquarium plants healthy and happy you should always use fertilizers. But some aquatic plants are undemanding which only needs natural food produced by the fish and other inhabitants. To grow aquarium plants successfully, you should need to know what types of fertilizers are used. In this case, three factors such as fertilizer, CO2, and light which influence your plant's growth. If you do not use proper fertilizers, your plants do not grow properly. In this case, they produce thin stems with pale and brittle leaves and finally, they probably will go to die if you only provide them CO2 and light instead of fertilizers.
