What is the Best Substrate For Planted Tank?
According to Wikipedia, the substrate of an aquarium is nothing but the material we use on the bottom of the aquarium. The substrate is all in all one of the most important factors for creating a healthy aquarium. It affects the water chemistry, filtration system and overall health of the inhabitants of your aquarium.
It also magnifies the beauty of an aquarium. There are many types of substrate such as gravel, river rocks, sand, play sand, aqua soil, etc. The type of substrate you need depends entirely on the type of your aquarium.
Suppose, for a normal community tank, you can either go for gravel, large rocks, sand or even a bare bottom tank. Bare bottom means that no substrate is used. For a planted tank, you should definitely go for an aqua soil such as ADA Amazonia. Lastly, for saltwater tanks or reef tanks, you will need live sand that is suited for that purpose.
Why do we need Aquarium Substrate?
There are thousands of reasons for using aquarium substrate. Here are some reasons illustrated for
1.The first and foremost reason for using substrate is that they help to begin the nitrogen cycle. A colony of beneficial bacteria grows on the substrate and starts the nitrogen cycle. Although, these bacteria grow on other stuff in your aquarium too, the significant amount resides on the substrate. The substrate also serves as a medium for growing roots of live plants. Commercially manufactured substrates even provide nutrition to the plants.
2.Substrate helps to imitate a natural environment for the fish. It is also mandatory for borrowing fishes. Bottom dweller fishes also like an aquarium with deep substrate. It also helps to calm the fishes.
3.Substrate can magnificently change the appearance of your aquarium. It increases the appealing aspect of your planted tank. Substrate is a must for creating planted tank. Substrate helps to create the perfect miniature natural environment inside your aquarium.
What are the benefits of using Aquarium Substrate?
·Substrate helps to start the nitrogen cycle.
·A significant amount of beneficial bacteria grows on the substrate.
·It creates a more natural habitat for the fishes.
·It increases the beauty of an aquarium.
·Substrate is a must for borrowing as well as bottom dwelling fishes.
·Without substrate, you can’t even think of a planted tank.
As mentioned earlier, there are many types of aquarium substrates to choose from. Here are some of the types:
Gravel:Gravel is one of the most common substrate choices for aquariums. Almost every pet shops use gravel on their aquarium. You can use it on any type of aquarium i.e. community aquarium, turtle tank etc. Even some aquatic plants can be grown on gravel too! Gravels are further divided into many sizes, colors and shapes. The main advantage of using gravel is they are cheap and can be used on almost any type of aquarium. However, the only drawback I can think of is, they are not the most beautiful substrate choice for aquarium. If you decide to choose gravel as your aquarium substrate, check beforehand if they are treated for aquarium or not!
Sand:The next common choice of substrate is sand. It is very popular among fishes that love to borrow inside the substrate. You can buy bulk amount of play sand and use them. But be sure to treat them before using. Wash them under running water for multiple times until the water doesn’t become cloudy. It is better if you can boil them before hand to ensure no harmful bacteria are living on it.
Crushed Coral:It is not as popular as a substrate choice like sand, but nevertheless, it is also an effective substrate for planted tank. Crushed coral can raise the pH of aquarium water as well as increase the buffering capacity. This substrate is very helpful if you keep species that like hard alkaline water such as some species of cichlids.
Large River Rock:Large river rocks can be used with gravels or on their own. They offer a more natural look to the aquarium. It is a natural substrate.
Marble:Marble is far from being a natural substrate. There are colorful marbles. Though they are not natural, they can provide a colorful look to your aquarium. Marbles are really useful when you have a fish that breeds egg scatteringly. The eggs fall into the spaces between marbles. As a result, the adult fishes can’t eat the eggs. So, the eggs remain safe.
Commercial soil:If you are keeping live plants in your aquarium, you must have commercial soil. They provide the required nutrition to live plants. Plants also can grow a root system inside the soil. These aquarium soils are very elegant looking. They slowly provide nutrition to the plants. You can also use other additives with a commercial soil.
How much substrate to use in the Planted Tank?
Normally, there is no set rule on how much substrate you should use. A general preference is to use about 1.5 to 2 inches of substrate in the aquarium. This provides enough substrate for beneficial bacteria to grow on the aquarium. This amount is also preferable for borrowing fishes. It is not recommended to go more than 2 inches of depth as gas pockets may for within the substrate.
If you are planning to keep live plants, then you may need to use further more substrate. Provide more substrate where you will keep a large amount of plants. You need to plan beforehand on where you’ll place the plants. Just provide more substrates in those places.
How to choose the best substrate for Planted Tank?
These are the characteristics of a good planted tank substrate:
·The substrate should be able to store nutrients and provide them to the plants.
·The significant amount of nutrient should be in the substrate, not in the water column.
·The substrate should slowly release the nutrient to live plants throughout a large amount of time. A good substrate contains both macronutrient and trace elements. The aquatic plants should be able to get a balanced nutrition profile from the substrate.
·There shouldn’t be any harmful chemicals inside the substrate. Discard the substrate immediately if there is any coating or dyeing on the soil.
·The granules should be porous and encourage strong growth of the plant roots.
·The soil shouldn’t degenerate much with time. A good planted tank substrate lasts for more than a year perfectly.
·Check carefully if the substrate is safe for fish, shrimp, snail, crab and other types of live stocks.
·Before buying a particular substrate, look on the internet and do some research. See what other customers have said about it. It’ll give you a pretty good idea about the substrate.
So, whenever you are looking for a new substrate, look for these characteristics. If the substrate doesn’t meet them, look for another one. Also, it helps if you do some research beforehand. Look what other customers have said about the substrate you are thinking to buy. Some research beforehand can save you a load of money.
Before putting the new substrate to your aquarium, always wash it thoroughly in lukewarm water first. This will help to remove all the dust and other foreign objects from the substrate. It is very important to use the cleanest substrate in your aquarium.
To clean properly, at first pour all of the substrates in a large bucket. Then fill the bucket with water. Rinse the substrate several times and pour down the water. Repeat these steps several times until the water runs clear.
The next step is to spread the substrate evenly on your aquarium. You should mound more amounts on places where you’ll place the live plants. The minimum depth of substrate should be one inch.
Choosing a nutrient rich substrate is the key to a successful planted tank. As there are thousands of substrates in the market right now, it is really difficult to choose a decent one. Most of them are really poor quality and may even harm your fishes. Wikihow has a pretty good article on how to start an aquarium with live plants.
