Reviews

ADA Aqua Soil Amazonia

This aqua soil is an excellent option for folks who have planted tanks with a wide variety of plants. It is inexpensive, all-natural, and most surely effective.

This aqua dirt has several advantages for your fish tank. One of our favorite features of this planted aquarium substrate is that it is comprised of earth-derived material that has been properly treated and is entirely natural.

This soil is extremely nutrient-dense and provides an ideal growing medium for aquatic plants. The granules are the appropriate size for aquatic plants to establish their roots and develop a healthy root system.

This planted aquarium substrate also reduces the pH of the water, which is beneficial for many aquatic plants. A lower pH level allows aquatic plants to absorb nutrients more quickly, allowing them to thrive.

In addition to making the water clean, adding a bottom layer, and not discoloring the water, it is an excellent choice.

This sort of substrate also aids to soften the water, which is an additional advantage.

Aqua Soil is an excellent substrate for planted aquariums with fish that thrive in softer water and lower pH.

We personally consider this to be the ideal soil for planted aquariums due to its high quality and organic composition.

Pros

  • Organic and nutrient-dense
  • Lowers pH level
  • Maintains water clarity
  • Softens water

Cons

  • Can't be vacuumed

Buyer's Guide

Substrate may appear to be a non-essential component of a planted aquarium, however this assumption is typically incorrect.

There are several advantages to utilizing substrate in your aquarium, so let's discuss them all today.

One of the most important advantages of employing substrate in planted aquariums is that it promotes plant growth. Unless they are artificial plants or floating plants, you will not be able to place live plants in your aquarium unless you have substrate.

In order to build a healthy root system, plants require substrate. Their roots are incapable of adhering to glass or acrylic, nor can they absorb nutrients from these materials. If you intend to keep plants in the aquarium, a quality substrate is an important must.

Substrate aids in simulating the natural habitat of the fish in your planted aquarium. Fish want to live in their natural environment, which clearly does not include a glass tank, but you may help them by providing a basic substrate.

River fish, lake fish, marine fish, and coral fish do not inhabit settings with glass substrates. This helps fish feel at home, decreases stress, and enables them to carry out their everyday activities.

Numerous fish like excavating substrate, creating tunnels, and foraging for food in substrate. Without substrate, fish cannot engage in their usual behaviors.

Substrates prevent excrement and fish waste from floating in the environment. Yes, it is necessary to periodically clean the substrate, but at least it prevents these undesirables from floating in the water and polluting it.

Diverse Forms Of Substrates

There are several varieties of substrates, each of which has somewhat different qualities and is best suited for a certain use.

Let's go on to discussing the various substrate options for your planted aquarium.

Aquarium Sand

Sand is an extremely popular substrate used in aquariums, second only to gravel in frequency.

If you have fish or other animals that prefer to burrow, seek for food, and bury themselves in sand, sand is a fantastic alternative.

Sand is a natural component of seas, coral reefs, and riverbeds. Small sand particles might block filters if they are stirred up excessively. Sand is also acceptable for plant growth.

Aquarium Gravel

Today, gravel is perhaps the most popular substrate used in aquariums. This material helps to simulate the natural surroundings of a number of natural ecosystems. It performs adequately in terms of plant growth.

Small gravel particles are nevertheless a suitable substratum for aquatic plants that require a healthy root system.

This type of gravel is far smoother than that found on the street, since smoother gravel particles will not harm your fish.

Desert Sand

Coral sand is an excellent choice for aquariums featuring marine or coral-dwelling fish. This is similar to a mixture of sand and gravel, as it resembles large sand grains but little gravel grains.

This substance tends to dissolve in water over time, increasing the pH. Coral sand is good if you have fish that require a higher pH level in the water.

Marble Fragments

This final substrate is also acceptable for usage. This material closely resembles coral sand, but contains more calcium carbonate.

This is a fantastic substitute for coral sand because it is less costly. It's rather porous, so it works well for plants, and it also filters out some of the water.

Soil

Soil is an ideal substrate for a planted aquarium. This material is often packed quite firmly and is ideal for aquariums with a high plant density.

It contains several nutrients essential for plant growth. Its dense composition makes it perfect for plants with robust root systems.

Marbles

We are not talking about typical marbles, but rather ones that resemble flat, spherical pancakes.

These are ideally suited for ornamental uses, although they may also be utilized for plant development.

However, they are devoid of nutrients and will have no effect on the water.

How Much Substrate Should You Use In An Aquarium With Plants?

By far, the ideal substrate for a planted arrangement is soil or a soil-like material. The reason for this is that compacted dirt or soil-like substrates are the most stable and thick of all substrates, making them an ideal medium for plant root development.

Furthermore, soil-like substrate has far more nutrients than other substrates, which plants require to grow large and healthy.

As a general rule of thumb, you should have at least one inch of substrate. Now, there is no exact maximum, but anything greater than 2 or even 2.5 inches is unnecessary.

1 inch of substrate is sufficient for tiny plants to build a healthy root system. In order to get a 1-inch substrate bed in your planted aquarium, you will need to utilize 1 pound of substrate every gallon of water.

FAQs

What is Substrate Used For?

Substrate can also assist in filtering out germs, poisons, and other pollutants. Substrate also prevents fish waste from floating freely around the fish tank by keeping it on the bottom.

Distinct substrates have different properties, and different substrates can assist contribute different nutrients to the water in order to maintain excellent water chemistry and beneficial microorganisms in a planted aquarium.

Additionally, a planted aquarium requires substrate for plant growth. The plant's roots cannot develop on the glass, so they require something to cling to.

How Should Aquarium Plants Be Planted In Gravel?

The process of planting aquarium plants on gravel is simple and requires little effort. Now, you should be aware that certain plants are more delicate than others, and how you plant them in gravel depends entirely on the plant itself.

Many plants just demand that you place the plant's roots in the gravel and lightly cover them, but be careful not to press down the gravel too much, as doing so might harm or crush the roots.

The roots of plants with delicate root systems may need to be secured without covering them with gravel, so they may grow into the gravel on their own.

How Should Substrate Be Laid?

This does not really important if you are only putting one type of substrate to your planted aquarium.

Simply determine how much substrate you need and how deep it must be, and then place it in the container.

If you are stacking gravel over sand, you should put approximately an inch or an inch and a half of sand and then gradually add the gravel. Be careful to take your time so you don't create a massive mess.

Are Substrates Required For Aquarium Plants?

Not all plants require substrate; the optimal aquarium soil will vary depending on the plant. Some plants like sand, others gravel, and others neither.

There are several aquarium plants that may be secured to rocks or driftwood, which are not the optimal substrate. There are also several plants that float on the surface of the water without being attached to anything.

How Can I Maintain a Clean Substrate?

Cleaning substrate is not very difficult. Ensure that your planted aquarium contains a few bottom feeders and snails, since they will consume leftover food, dead plants, and algae.

In addition, regular water changes will avoid the accumulation of detritus on the substrate. Additionally, a powerful filtration system that removes the majority of particles from the water will be useful.

You should also avoid overfeeding your fish so that they do not create an excessive amount of trash. So that you can manually remove the debris, a gravel vacuum for aquariums is a must-have (our top 5 picks are detailed in this post).

When Can Fish And Plants Be Added?

This is everything related to the nitrogen cycle. The nitrogen cycle enables the growth of bacteria in water, which aids in the removal of pollutants.

In order for these bacteria to colonize the substrate, you should wait around six weeks before adding fish to the aquarium. You must wait until at least one nitrogen cycle is complete.
