The substrate that you choose for your planted aquarium not only improves the visual appeal of your tank but also provides safety to the plants and aquatic animals inside. You have to select the right quality of substrate to encourage plant growth and to keep the tank free from germs. Your aquarium will be healthy when you choose a healthy substrate.

Today, hobbyists have a lot of options before them when they set out to choose the right substrate for their aquariums. Different materials, colors, forms, and sizes of freshwater substrates are available today. Gone are the days when sand and gravel were the only types of substrates used in aquariums.

In this article, we will tell you about the substrates that you can consider for your planted aquarium and why they will help the overall health of the plants and animals inside. Before dwelling on the top models, we will give you a brief overview of the importance of choosing the right substrate, so that you are informed about the same.

Why is a Freshwater Aquarium Substrate Important?

If you are wondering why a planted tank substrate is very important, this is the section that you have to read. Substrates are used for four important reasons. They are:

Biological filtration purposes–Your aquarium plants need substrate as they are prone to witness a lot of plant debris, food leftovers, and the waste of the fishes. These need to be eliminated to safeguard the overall hygiene of the aquarium. When you choose the right freshwater substrate, good bacteria grow and colonize on them. These colonies then naturally eliminate the waste products, thereby keeping the tank absolutely safe.

Creating natural habitat for the fishes – Substrates are available in different types to mimic the natural habitat of the different types of fishes. This will make the fishes feel comfortable when they are inside the tank so that they are stress-free and healthy.

Encourage the growth of plants–When you have a planted aquarium, it becomes imperative for you to invest in the right substrate. This is because the plants grow well on these aquatic substrates, thereby keeping your tank fresh and odor-free.

Decorative purposes – Last, but definitely not least, a substrate is important to decorate your aquarium and make it look visually appealing to your eyes.

Choosing the right substrate for a planted tank is quite a challenge because of the sheer magnitude of products in the market today. This is why, we have compiled the best 8 substrates herewith, with a brief review of each one of them. After reading this article, you will have a clear idea about choosing the specific substrate that fits your requirements the best.

    Factors to consider while buying an aquarium substrate

    Aquarium substrate gives a lift to the whole interior space and most aquarists would rather have one laid out at the bottom of the tank than leave it bare – despite the fact that the latter (i.e., bare-bottom) makes for easy and time-saving clean-up. Moreover, the substrate is needed if an aquarist decides to have a planted aquarium as it will serve as some sort of nutrient reservoir.

    If you have been wondering about the factors you need to consider while buying a planted tank substrate, then read on.

    • Material: The substrate material is of great significance and should be the first factor to weigh in on; for one, the life/well-being of your fish may depend on it and then, the effort and time devoted towards monitoring the conditions within the tank could either be reduced or increased as a result of the type of substrate used. Again, you should consider buying a substrate that would allow your fish some good degree of freedom and will not hamper its lifestyle. For instance, fish species with burrowing tendencies will appreciate a sand substrate better than any other.
    • Chemical reactivity: This is another vital aspect that you cannot afford to overlook as different substrate types react differently with the water in the aquarium. While gravel does not have any significant effect on the pH of the water, others like aragonite substrate can create an alkaline pH as the value [of the water pH] gets pushed up. Hence, you will need to buy a substrate that is well-suited for your fish species or aquarium set-up – whether marine or freshwater.
    • Ease of cleaning: Substrates also vary with respect to how easy they are to clean and maintain – though adding a good 5-gallon filtration system in an aquarium contributes immensely to the process. By the way; the sand substrate is known to be the easiest to clean of the lots that you could possibly use.
    • Aesthetics: While this may be the least of anyone’s concern, it does make sense to select a substrate that will make the aquarium somewhat colorful. There are a number of colored substrates that can help you actualize this.

    How to DIY planted aquarium substrate at home

    Several aquarium substrates are readily available at the store, but for one case or the other, there are a few aquarists that want to make planted aquarium substrate at home. And, the truth is that such it remains as effective as the conventional ones, especially as it presents the plants with a surface required to take root.

    It is for those that may be interested in making a DIY planted aquarium substrate that we have elected to put forth this write-up.

    Making a DIY planted aquarium substrate

    • Materials required: Garden soil, Pottery clay, Baking tray, Strainer, Stirring rod, and Container.

    Procedure:

    • Collect the top layer of the soil into a container, breaking up whatever clog that you may see. Add water to the container to about 2.5 – 5 cm above the soil level. FYI; you should stir the soil as you add water to ensure good saturation. This should then be left for 2 days.
    • Drain the water from the mixture after 2 days; add water again and leave for another 2 days.
    • The saturated soil should then be spread onto the baking tray and allowed to dry out under the sun.

    N.B: You may, however, need to turn back the dried soil into the container, add water and leave for 2 days before draining again to spread unto the tray; this would help to suppress the effects of the fertilizer that may be present within the soil.

    • Sieve the dried soil with the aid of the strainer and then put it back into the container.
    • Now, add pottery clay – it should be one-tenth of the quantity of the soil – therein and mix with warm water, stirring to achieve a paste-like form.
    • With the soil substrate ready, the next step is to pour it into the tank. But before then, you must have spread potassium chloride over the bottom of the tank.
    • Create a layer of gravel over the soil substrate, and gently add water (refill) to the aquarium without agitating the (soil) substrate thereof. You can thereafter add your plant, making sure it is rooted therein.

    Bottom Line

    Though the Spectrastone Shallow Creek Substrate is definitely not our first choice for planted aquariums, we still see no reason why you shouldn’t try it out. It is affordable and easy to use as well. So, you could try it to see how it works on your tank.
