The success of any aquarium or aquascape depends on the planted tank substrate used. Aquatic plants, just like garden plants, have a complex root system which helps them absorb the necessary nutrients they need for their survival. These nutrients play major role in the health, growth rate and coloration of aquarium plants. Substrates that are rich in nutrients can help combat the growth of unwanted algae by allowing your plants to grow and overtake the growth of these weeds, absorbing all the nutrients, and killing them by starving them to death.

They are many manufacturers of plant substrates today which are popular for their success and good prices. However, the competition in the substrate market is overwhelming as many companies are trying to outsmart each other by offering unique products with extra features. This article takes a look at some of these brands and the product they offer.

Eco Complete Planted Black Aquarium Substrate - Awesome live plant gravel

This substrate outperforms other substrates with its greatly enriched natural soil formula that mimics the rich soil in Hawaii, Costa Rica and Bali – the regions are known for the lush and exuberant growth of the plants.

The secret of this substrate lies in the fact that it is composed of rich basaltic volcanic soil that contains iron, calcium, sulfur, magnesium, potassium and a host of another element to effectively nourish your aquatic plants. Besides, this substrate also contains live heterotrophic bacteria that convert fish waste to natural food for aquatic plants hence establishing a natural biological balance that will make cycling a new aquarium safe and faster.

Pro Tip

The eco complete aquarium substrate has the right biological and mineral composition, thus giving you the desired luxuriant aquatic plant growth and preventing the growth of unwanted algae. The substrate contains natural iron with no artificial dyes, paints or chemical coatings, so it will not compromise your tank water quality. If you are finding a cheap, reliable and easy-to-use planted tank substrate, this is the perfect choice.

Fluval plant and shrimp stratum is the right substrate for stimulating the healthy growth of aquatic plants in a freshwater aquascape. Being made from mineral-rich volcanic soil plus the addition of Fluval micronutrients, the Fluval soil will ensure a full complement of essential micro and macro nutrients for your plants to grow.

Besides providing your plants with many nutrients, this soil is made with granules that make it easier for plant roots to penetrate throughout the substrate. This allows the plant to absorb a variety of available important nutrients from the soil to flourish. By this design, the Fluval stratum also protects newborn shrimps by providing them the ideal refuge to escape predation until they are big enough to roam.

Unlike the Eco Complete aqua soil containing live microorganisms, the Fluval soil encourages the growth of nitrifying bacteria with its light, non-compacting porous soil structure. The nitrifying bacteria can easily colonize the vast porous surface, this will provide the optimal water quality for aquatic plants.

Pro Tip

The Fluval substrates have been carefully made so you should not worry as it will not compromise your water clarity, it even controls organic discoloration which is usually present with the use of natural driftwood. Moreover, the properties of this stratum support a natural to slightly acidic pH. This is ideal for most plant and tropical fish species and for shrimps that are normally kept in planted aquariums.

The red color of the product is non-toxic for your aquarium life because it is 100% natural and contains no artificial dyes or additives. This soil also provides plenty of trace elements including iron for nourishing your aquatic plants, so you don’t need to supplement another laterite substrate.
