Nisso Shrimp Soil Black 8L – Active Aquarium Substrate

Nisso Shrimp Soil Black 8L is a premium Japanese aquarium substrate developed for freshwater shrimp and planted aquariums. Designed to help lower pH and soften aquarium water, this active shrimp soil creates conditions particularly suited to Crystal Red Shrimp, Crystal Black Shrimp and other Caridina species that prefer soft, slightly acidic water.

Unlike ordinary inert aquarium gravel, Nisso Custom Shrimp Soil actively influences water chemistry. Its mineral-rich clay composition helps support more suitable conditions for sensitive shrimp, while the natural black colour provides a beautiful contrast against colourful shrimp and green aquarium plants.

The generous 8-litre bag is ideal for larger shrimp aquariums, planted aquascapes or tanks requiring a deeper substrate layer. The soil is ready to use straight from the bag, with no pre-washing required.

Why Choose Nisso Shrimp Soil Black?

• Designed for Caridina shrimp: Helps create softer, mildly acidic water conditions preferred by many Crystal Red, Crystal Black and Bee Shrimp varieties.
• Active pH buffering: Naturally helps lower aquarium pH and reduce water hardness.
• Japanese-made substrate: Developed specifically for freshwater shrimp and planted aquarium applications.
• Montmorillonite and bentonite clays: Mineral clay components help support the substrate's physical and chemical properties.
• Low-ammonia formulation: Developed to minimise initial ammonia release compared with some more nutrient-rich aquarium soils.
• Mixed-size granules: Helps create a more practical substrate surface for adult shrimp and shrimplets.
• Supports beneficial bacteria: Porous granules provide additional surfaces for bacterial colonisation.
• Suitable for aquatic plants: Supports rooted plant growth in compatible planted aquariums.
• Natural black appearance: Provides excellent contrast for colourful freshwater shrimp and green plants.
• No pre-rinsing required: Can be added directly to a new aquarium without washing.

Active Shrimp Soil for Soft, Acidic Water

Many popular Caridina shrimp originate from or have been selectively bred for aquarium conditions involving relatively soft, mildly acidic water.

Nisso Shrimp Soil helps create these conditions by influencing the chemistry of aquarium water. It is designed to lower pH and soften water, making it particularly useful for shrimp aquariums where water parameters need to be managed carefully.

The Australian distributor identifies an indicative pH range of approximately 5.5–6.8. However, the actual pH achieved depends on your source water, carbonate hardness, mineral content and aquarium conditions.

Important: Active substrate does not guarantee a fixed pH. Test your aquarium water regularly and use suitable source water and remineralisation products for the shrimp species being kept.

Ideal for Crystal Red Shrimp and Other Caridina

Nisso Shrimp Soil Black is especially suited to freshwater shrimp that prefer low carbonate hardness and mildly acidic conditions.

It can be used in suitable setups for:

• Crystal Red Shrimp: Helps create the softer, acidic conditions generally preferred by this selectively bred Caridina variety.
• Crystal Black Shrimp: Supports aquarium environments with similar water-parameter requirements to Crystal Red Shrimp.
• Bee Shrimp: Suitable for many soft-water varieties when combined with appropriate water preparation.
• Other compatible Caridina shrimp: Useful where the selected species requires active soil and controlled water chemistry.

Not every shrimp species needs active soil. Cherry Shrimp and many other Neocaridina varieties generally tolerate a wider range of neutral to moderately alkaline conditions. An active, pH-lowering substrate may be unnecessary or unsuitable if it pushes water outside their preferred parameters.

Specially Developed Clay-Based Granules

Nisso Custom Shrimp Soil contains mineral clays, including bentonite and montmorillonite, which contribute to its performance as an active aquarium substrate.

These materials can interact with dissolved substances in water and provide surfaces for beneficial microorganisms to colonise.

The shrimp-specific formulation also uses mixed granule sizes to create a substrate surface suited to small shrimp and their grazing behaviour.

As an active substrate, it can contribute to water-parameter management, but it does not replace an established biological filter or regular aquarium maintenance.

Supports Healthy Planted Aquarium Growth

Nisso Shrimp Soil Black is also suitable for planted aquariums, providing a natural-looking base for many popular freshwater aquarium plants.

It can be used with compatible rooted plants such as:

• Cryptocoryne: Popular rosette plants that benefit from a suitable planted substrate.
• Staurogyne repens: A compact foreground and midground plant for aquascaping.
• Rotala: Stem plants suited to many planted aquarium layouts.
• Eleocharis hairgrass: A carpeting plant that can spread through suitable substrate.
• Other freshwater aquatic plants: Suitable species can be grown according to their individual light, nutrient and CO2 requirements.

Plant growth depends on lighting, fertilisation, water parameters and species requirements. While the soil supports planted aquariums, additional nutrients may be necessary over time.

How to Use Nisso Shrimp Soil Black

1. Clean and prepare the aquarium before adding substrate.
2. Do not wash or rinse the soil. Rinsing can damage the granules and increase cloudiness.
3. Pour the soil directly into the aquarium and distribute it to the desired depth.
4. Create a gentle slope towards the rear if required for your aquascape.
5. Position driftwood, rocks and other hardscape materials securely.
6. Plant suitable aquarium plants carefully into the substrate.
7. Fill the aquarium slowly, directing water onto a clean plate or protective surface to minimise disturbance.
8. Install and operate your aquarium filter.
9. Allow the aquarium to establish and test ammonia, nitrite, pH, GH and KH before introducing sensitive shrimp.

Important: Use the soil as a standalone active substrate where possible. Covering it with an inert gravel or sand layer may interfere with its intended performance.

Do You Need to Cycle an Aquarium with Nisso Shrimp Soil?

Yes. Even though Nisso Shrimp Soil is formulated for relatively low initial ammonia release, a newly established aquarium still requires a working biological filtration system.

Beneficial bacteria need time to colonise the filter and other aquarium surfaces so they can process ammonia and nitrite.

Before introducing sensitive Caridina shrimp:

• Confirm ammonia and nitrite are at safe, undetectable levels using suitable tests.
• Check that pH, GH and KH are appropriate for the shrimp variety.
• Ensure water temperature is stable.
• Use appropriately remineralised water where required.
• Allow the aquarium to develop a suitable biofilm and grazing environment.

Do not assume that low-ammonia soil makes a new aquarium immediately safe for shrimp.

How Much Aquarium Does an 8L Bag Cover?

Coverage depends on the aquarium footprint and the desired substrate depth.

As a general guide, an 8L bag provides approximately:

• 60 x 30cm aquarium: Around 4.4cm average substrate depth.
• 60 x 36cm aquarium: Around 3.7cm average substrate depth.
• 90 x 30cm aquarium: Around 3cm average substrate depth.

These figures are approximate and assume an even layer with no displacement from rocks, decorations or other hardscape materials.

A sloping substrate, deeper planting areas or a more complex aquascape may require additional soil.

How Long Does Active Shrimp Soil Last?

Active shrimp soils have a limited ability to buffer water chemistry. Over time, this buffering capacity gradually becomes exhausted.

The lifespan depends on the carbonate hardness of your source water, water-change frequency, mineral content and overall aquarium conditions.

Monitor pH and KH regularly. If the substrate no longer maintains the required conditions, replacement or a carefully planned aquarium reset may be necessary.

For established shrimp colonies, avoid sudden large substrate changes that could disturb beneficial bacteria or water chemistry.

Nisso Shrimp Soil vs Ordinary Aquarium Gravel

Ordinary inert gravel is primarily used for decoration, anchoring plants and providing a surface for beneficial bacteria.

Nisso Shrimp Soil Black is different because it is an active aquarium substrate designed to influence pH and water hardness.

This makes it particularly useful for sensitive shrimp requiring soft, acidic conditions, while inert gravel or sand may be preferable for aquariums where maintaining neutral or alkaline conditions is the goal.

Frequently Asked Questions

Is Nisso Shrimp Soil suitable for Crystal Red Shrimp?

Yes. Nisso Shrimp Soil Black is designed for freshwater shrimp that prefer soft, mildly acidic water, including Crystal Red Shrimp and other compatible Caridina varieties. Water parameters should still be checked before adding shrimp.

Does Nisso Shrimp Soil lower aquarium pH?

Yes. It is an active substrate designed to lower pH and soften aquarium water. The final pH depends on source water chemistry, carbonate hardness and aquarium conditions.

Do I need to wash Nisso Shrimp Soil before use?

No. The manufacturer-supplied guidance recommends using the soil directly from the bag without washing. Rinsing may damage the granules and increase cloudiness.

Can I use Nisso Shrimp Soil with Cherry Shrimp?

Cherry Shrimp generally do not require strongly acidic conditions. Nisso Shrimp Soil may be used only where the resulting water parameters suit the shrimp being kept. An inert substrate is often a simpler choice for Neocaridina aquariums.

Is Nisso Shrimp Soil suitable for aquarium plants?

Yes. It can be used in planted freshwater aquariums, providing a substrate for rooted plants. Additional fertilisation may be required depending on plant needs and aquarium conditions.

Can I add shrimp immediately after installing Nisso Shrimp Soil?

No. A newly established aquarium should be properly cycled and tested before introducing sensitive shrimp. Check ammonia, nitrite, pH, GH and KH and allow the system to stabilise.

How much area will an 8L bag cover?

As an approximate guide, 8 litres provides a 4.4cm substrate layer in a 60 x 30cm aquarium or a 3cm layer in a 90 x 30cm aquarium, before accounting for hardscape displacement.

How long will Nisso Shrimp Soil buffer pH?

Its active buffering capacity is limited and gradually declines with use. Lifespan varies according to source water hardness, water changes and aquarium conditions. Monitor pH and KH regularly.
