Its 3mm granules support robust plant root development while naturally softening and acidifying water to create an ideal environment for tropical fish and dwarf shrimp. The substrate also helps clarify and detoxify water, enhancing both aquatic health and visual appeal. ## Description Ultum Nature Systems has partnered with Marfied to bring you Ultum Nature Controsoil. UNS Controsoil is an andisol based substrate created from the volcanic ash of Mount Aso in Japan. Choosing the right substrate is a vital component for a successful planted aquarium. It allows plants to flourish while buffering the water to optimum levels for certain freshwater livestock. Proper aquarium substrate is paramount to successfully growing healthy aquatic plants. Controsoil absorbs impurities in your water column to provide a healthy environment for livestock. The texture and porosity provide the perfect medium for plant roots to latch onto. This soil is specifically designed for planted aquariums and shrimp keeping without excessive ammonia, which can lead to algae during initial use. Ultum Nature Controsoil does not require any rinsing and won't cloud your water when properly used. For the best results, place your Controsoil into your aquarium prior to adding water. Add water slowly without stirring up the soil For planted tanks, we recommend using UNS Controsoil with UNS Plant Food fertilizers. Directions: Place the substrate in to an empty aquarium. When filling the aquarium with water, place a dish or other item to disburse the water flow and minimize disruption to the substrate layer. How much soil do I need? Length x Width x Desired Substrate Height (in inches), Divided by 60 = Liters of soil needed. Made in Japan. Available in 2 colors: Black and Brown. Available in three granule sizes: Normal (5mm), Fine (3mm), and Extra Fine (1mm). Available in three bag sizes: 1L, 3L, and 10L. ## Features - Formulated for freshwater planted aquariums, tropical fish, and freshwater dwarf shrimp. - Helps clarify and detoxify water - Dark "Black" color - Naturally acidifies and softens aquarium water - Fine granule size (~3mm) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07C2KYXBB | | Brand Name | Ultum Nature Systems | | Customer Reviews | 4.4 4.4 out of 5 stars (63) | | Global Trade Identification Number | 00851302008535 | | Manufacturer | Marfied | | Unit Count | 1.00 Count | ## Product Details - **Brand:** Ultum Nature Systems - **Global Trade Identification Number:** 00851302008535 - **Unit count:** 1.00 Count ## Images ![Ultum Nature Systems Controsoil Freshwater Planted Aquarium Substrate - Fine Black (3 Liter) - Image 1](https://m.media-amazon.com/images/I/71Hka6eVN9L.jpg) ![Ultum Nature Systems Controsoil Freshwater Planted Aquarium Substrate - Fine Black (3 Liter) - Image 2](https://m.media-amazon.com/images/I/71GSOW2U4vL.jpg) ![Ultum Nature Systems Controsoil Freshwater Planted Aquarium Substrate - Fine Black (3 Liter) - Image 3](https://m.media-amazon.com/images/I/61pIO8XilLL.jpg) ![Ultum Nature Systems Controsoil Freshwater Planted Aquarium Substrate - Fine Black (3 Liter) - Image 4](https://m.media-amazon.com/images/I/81dcLtaoQwL.jpg) ![Ultum Nature Systems Controsoil Freshwater Planted Aquarium Substrate - Fine Black (3 Liter) - Image 5](https://m.media-amazon.com/images/I/81GWF8pjiSL.jpg) ## Frequently Bought Together - Ultum Nature Systems Controsoil - Planted Aquarium Substrate Soil for Fish Tank, Natural Freshwater Aquatic Plants, Shrimp, Aquascape - Black (Fine, 3 Liters) - API ROOT TABS Freshwater Aquarium Plant Fertilizer 0.4-Ounce 10-Count Box - API FRESHWATER MASTER TEST KIT 800-Test Freshwater Aquarium Water Master Test Kit, White, Single, Multi-colored --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/375312934-ultum-nature-systems-controsoil-freshwater-planted-aquarium-substrate-fine-black](https://www.desertcart.hr/products/375312934-ultum-nature-systems-controsoil-freshwater-planted-aquarium-substrate-fine-black) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-23*
