About us

The company Danesh Zist Darya, under the commercial brand Deep Ocean, was established in 2015. With a team of experts in marine biology and chemistry, the company began producing specialized products for marine ecosystems. At Deep Ocean, our goal is to provide scientifically-backed, standard, and reliable products that facilitate proper management of water in marine and planted aquariums. These products are the result of up-to-date scientific knowledge, professional expertise, and adherence to ethical business principles. The technology used in the production of marine aquarium salt is Spray Drying, which has been utilized for the first time in Iran and Asia. This advanced method ensures the production of dry and uniform products that meet the highest global standards. The raw materials used in Deep Ocean products are of extremely high purity and are tested for harmful elements such as phosphate, nitrate, and heavy metals before entering the production process. Only materials that meet our strict standards proceed to production. Danesh Zist Darya has a quality control laboratory equipped with advanced analytical devices such as AAS, HPLC, and ICP-MS, ensuring that its products are manufactured with precision and quality that exceed existing standards. These advanced tools allow for detailed examination of raw materials and quality control of the final product, guaranteeing the superior quality of Deep Ocean products compared to similar offerings in the market. Our dedicated support team is ready to address customer inquiries about products and their usage. We believe that direct communication with customers and meeting their needs is one of the key principles of success. Additionally, all of our products are batch-numbered, and samples of each batch are stored for two years to ensure traceability and provide verification if needed. Deep Ocean products are formulated based on the latest scientific research and global data. Our goal is to use the purest raw materials in concentrations that have positive and lasting effects on the health of aquarium systems and living organisms. Every detail of the product formulation process is carefully scrutinized to ensure the final product delivers optimal performance while being fully compatible with the aquarium ecosystem. Deep Ocean products are designed to cater to all levels of expertise, from beginner to advanced aquarists. We offer a comprehensive range of products to address various needs, from simple coral and plant feeding systems to advanced nutrient management systems. Our goal is to create precise chemical balance in aquarium water to maintain a healthy and stable environment for corals, fish, and plants. Deep Ocean is committed to stringent quality control at every stage of production. All of our products are manufactured and packaged using specialized equipment. Our production facilities adhere to strict health and hygiene standards to ensure that every product leaving the facility meets the highest global standards. Additionally, in the production of liquid products, we use ultra-pure water that is treated through advanced reverse osmosis and multi-stage deionization systems. This process guarantees that Deep Ocean liquid products are fully aligned with the specifications stated on their labels. We believe the quality of water used in liquid products directly impacts their performance, and therefore, this phase of production receives special attention. Deep Ocean products are formulated with high concentrations, allowing aquarists to adjust the water chemistry of larger volumes of aquarium water with each unit. This feature makes Deep Ocean products an economical and efficient choice for aquarists. We believe that quality should be paired with efficiency, and this philosophy is evident in the design of our products. Deep Ocean formulations are designed to mimic the parameters of natural seawater. We use up-to-date data on the composition of natural seawater to create products with precisely balanced ionic ratios and element concentrations. This accuracy ensures that the difference between our products and natural seawater is imperceptible. Our goal is to create products that not only support the health of living organisms but also replicate natural conditions. At Deep Ocean, we are committed to ethical principles and honesty in business. All of our products are created with a commitment to ethical practices, scientific standards, and respect for our customers. This is our promise to you: every Deep Ocean product you purchase is the result of our dedication to delivering the highest possible quality.
