With a powerful blend of calcium, strontium, magnesium, and potassium, it mimics the natural ratios found in aragonite, enhances alkalinity, and stabilizes pH, all while being free of harmful phosphates and silicates. This 500-ml liquid solution is suitable for all life stages and serves as an economical alternative to automated calcium reactors. ## Description Brightwell Aquatics Liquid Reef has twice the calcium relative to carbonates as compared to natural aragonite, making it a very powerful calcium source. The active components of Liquid Reef are provided by a combination of sources and include natural aragonite, increasing the solubility of the solution and the effectiveness of the method. Silicate- and phosphate-free. Examples of reef-building organisms familiar to hobbyists are: stony corals and their allies; molluscs including clams (bivalves) and snails (gastropods); tube worms that secrete calcareous burrows; and calcareous algae such as coralline, Halimeda, and Penicilus. These organisms require that the components of aragonite be in adequate concentrations if they are to thrive, regardless of how perfect the remainder of their environment is. The advantage to this method of supplementation is that one product may be used to establish and maintain water parameters conducive to reef formation. Note that target ion-specific supplementation may be called for in some aquaria, depending upon stocking density of reef-building organisms and environmental conditions within the system. Additionally, hobbyists may choose to use Liquid Reef in conjunction with other methods of calcium, strontium, magnesium, and carbonate supplementation as a means of diversifying their dosing routine. The rate at which calcium and carbonates are extracted from the water is determined by the stocking density of reef-building livestock, type of lighting, and other conditions; therefore, each aquarium will have different requirements for the rate of supplementation. Aragonite composition is seen to vary slightly between regions; the specific ratios of target ions in Liquid Reef are based upon data available for aragonite originating in the Tropical Atlantic. ## Features - Complete source of the elements and molecules that are directly used by corals, clams, and other reef-building invertebrates and organisms to create skeletal material and grow - Provides calcium (140 000 ppm) strontium magnesium and potassium in approximately the same ratios in which they occur in aragonite - Very strong source of carbonates (derived from aragonite) - Increases alkalinity to help stabilize pH - Free of phosphate, silicate, and organic material. May be used as an inexpensive alternative to automated calcium reactor systems ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001DD13WC | | Allergen Information | Sulphites Free | | Brand Name | Brightwell Aquatics | | Customer Reviews | 4.7 4.7 out of 5 stars (89) | | Global Trade Identification Number | 00810086010325 | | Included Components | Liquid Reef | | Item Form | Liquid | | Item Type Name | Water Conditioner | | Item Weight | 1 Pounds | | Liquid Volume | 500 Milliliters | | Manufacturer | Brightwell Aquatics | | Manufacturer Part Number | LRF500 | | Model Number | LRF500 | | Number of Items | 1 | | Pet Type | Fish | | Target Species | Fish | | UPC | 810086010325 | | Unit Count | 1 Count | ## Product Details - **Brand:** Brightwell Aquatics - **Item form:** Liquid - **Item weight:** 1 Pounds - **Liquid volume:** 500 Milliliters - **Unit count:** 1 Count ## Images ![Brightwell Aquatics Liquid Reef - Concentrated Reef Builder for Coralline Algae, Corals, Clams & Other Marine Invertebrates, 500-ml - Image 1](https://m.media-amazon.com/images/I/71odxOdTq8L.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - Brightwell Aquatics Liquid Reef - Concentrated Reef Builder for Coralline Algae, Corals, Clams & Other Marine Invertebrates, 500-ml - Brightwell Aquatics MicroBacter7 Complete Bioculture for Fish Tank or Aquarium - Populates Biological Filter Media for Saltwater and Freshwater Fish - Aquarium Water Treatments, 16.9 fl oz - Brightwell Aquatics MicroBacter Clean - Microbial Culture & Enzyme Blend Fish Tank Cleaner - Cleans Live Rock Surfaces for Saltwater Fish Habitats - Aquarium Water Treatments, 8.45 fl oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nl/products/391130645-brightwell-aquatics-liquid-reef-concentrated-reef-builder-for-coralline-algae](https://www.desertcart.nl/products/391130645-brightwell-aquatics-liquid-reef-concentrated-reef-builder-for-coralline-algae) --- *Product available on Desertcart Netherlands* *Store origin: NL* *Last updated: 2026-09-19*
