Review: Received fresh product that expires in 2027 ! - I like Red Sea and the 5 liter bottles are a great savings! What I do not like is old product or product expiring very soon. Happy to report that this was very fresh product! Review: Authentic - I only use about 30ml a day so this is still economical. I tried buying the powder on desertcart and what I received was counterfeit (it was used, filled with baking soda, and resold). This container came sealed. ## Features - Quality And Performance Driven Products For Your Pet - Tested For Safety And Health - Provide A Better Quality Of Living For Your Pet With Red Sea - Package Dimensions: 4.96062992125984" L X 7.79527559055118" W X 11.4173228346457" H ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B011UMNKS0 | | Allergen Information | Apple Free | | Best Sellers Rank | #62,272 in Pet Supplies ( See Top 100 in Pet Supplies ) #516 in Fish Medication & Health Supplies | | Brand | Red Sea | | Brand Name | Red Sea | | Customer Reviews | 4.7 out of 5 stars 47 Reviews | | Global Trade Identification Number | 00730773220250 | | Item Form | Liquid | | Item Type Name | Aquarium Supplies | | Item Weight | 454 g | | Item form | Liquid | | Item weight | 454 g | | Liquid Volume | 5 Liters | | Liquid volume | 5 Liters | | Manufacturer | Pro-Motion Distributing - Direct | | Manufacturer Part Number | 63322025 | | Model Number | 63322025 | | Pet Type | Fish | | Target Species | Fish | | UPC | 730773220250 | | Unit Count | 5000.0 Milliliters | | Unit count | 5000.0 Milliliters | ## Product Details - **Brand:** Red Sea - **Item form:** Liquid - **Item weight:** 1 Pounds - **Liquid volume:** 5 Liters - **Unit count:** 5000.0 Milliliters ## Images ![Red Sea Reef Foundation B Alkalinity (KH) Supplement, 5 L - Boosts Carbonate Levels for Strong Coral Skeletons in Reef & Marine Aquariums - Image 1](https://m.media-amazon.com/images/I/71XtwFRr2mL.jpg) ![Red Sea Reef Foundation B Alkalinity (KH) Supplement, 5 L - Boosts Carbonate Levels for Strong Coral Skeletons in Reef & Marine Aquariums - Image 2](https://m.media-amazon.com/images/I/61DbhrwHHaL.jpg) ![Red Sea Reef Foundation B Alkalinity (KH) Supplement, 5 L - Boosts Carbonate Levels for Strong Coral Skeletons in Reef & Marine Aquariums - Image 3](https://m.media-amazon.com/images/I/81wICs0grEL.jpg) ![Red Sea Reef Foundation B Alkalinity (KH) Supplement, 5 L - Boosts Carbonate Levels for Strong Coral Skeletons in Reef & Marine Aquariums - Image 4](https://m.media-amazon.com/images/I/71plVaLV2mL.jpg) ![Red Sea Reef Foundation B Alkalinity (KH) Supplement, 5 L - Boosts Carbonate Levels for Strong Coral Skeletons in Reef & Marine Aquariums - Image 5](https://m.media-amazon.com/images/I/813S2x5uOnL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Received fresh product that expires in 2027 ! *by S***G on 8 April 2023* I like Red Sea and the 5 liter bottles are a great savings!
