Designed specifically for freshwater planted aquariums, it naturally acidifies and softens water while detoxifying impurities. Its fine 3mm granules provide an optimal medium for plant root growth and aquatic livestock health, requiring no rinsing and minimizing initial cloudiness for a hassle-free setup. ## 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. Review: Nice - Good soil Review: Truly easy to use - minimal clouding - This was super easy to add to the tank. There was the initial clouding but a water change and letting the filter do it's thing and after less than 30 minutes, the tank was clear. Initial impressions are great. Of note, brown is a little darker than expected, but in a good way. If you're looking for light brown, this is definitely not light brown. ## 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 | Ultum Nature Systems | | Brand Name | Ultum Nature Systems | | Customer Reviews | 4.5 out of 5 stars 69 Reviews | | Global Trade Identification Number | 00851302008535 | | Manufacturer | Marfied | | Unit Count | 1.00 Count | | Unit count | 1.00 Count | | Volume | 3 Liters | ## Product Details - **Brand:** Ultum Nature Systems - **Global Trade Identification Number:** 00851302008535 - **Unit count:** 1.00 Count ## Images ![Controsoil Freshwater Planted Aquarium Substrate - Fine Black (3 Liter) - Image 1](https://m.media-amazon.com/images/I/71Hka6eVN9L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice *by A***N on 22 April 2026* Good soil ### ⭐⭐⭐⭐⭐ Truly easy to use - minimal clouding *by E***E on 22 January 2025* This was super easy to add to the tank. There was the initial clouding but a water change and letting the filter do it's thing and after less than 30 minutes, the tank was clear. Initial impressions are great. Of note, brown is a little darker than expected, but in a good way. If you're looking for light brown, this is definitely not light brown. ### ⭐⭐⭐⭐⭐ If you want an active soil for your aquarium, this one is it. *by S***N on 13 November 2023* Expensive, but then I haven't found one that isn't. No ammonia released (a huge plus). Comes in different size granules (genius!) No washing was required at all, and the slight haze during the tank fill quickly dissipated. (Pour it into the tank gently, add your water slowly). The perfect aquasoil. ## 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.tn/products/375312934-controsoil-freshwater-planted-aquarium-substrate-fine-black-3-liter](https://www.desertcart.tn/products/375312934-controsoil-freshwater-planted-aquarium-substrate-fine-black-3-liter) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-22*
