NO is very easy ... you need patience and understanding. For l amount of criticism I've read: many people do not know how to use or simply not read the instructions. Already today: after almost five reading TEST of each: excellent and very good .. I checked with other TEST (API SEACHEM) and are very even. The material is very good briefcase; Sturdy appropriate, arrived quickly, very good price relationship. It is a very good product for REEF aquarium. If you are a keen aquarist should have the equipment on hand. I have NO complaints Review: Great kit, seems consistent and more accurate than others - I like the design of this kit. I've been using salifert which has been consistent but when I dosed my alkalinity with the red sea I noticed it was .5 Lower than the salifert. I tested 3 times with the red sea and each time was 8.4. I think the red sea is probably more accurate. Although the salifefrt may be off a little it's still consistent and with saltwater consistency is the key. I like both test kits but I think I prefer the red sea. ## Features - Saltwater Reef Foundation Pro Multi Test Kit - Includes High Accuracy Titration Tests For The Accurate Measurement Of The Elements Calcium, Magnesium And Alkalinity (KHz) - All of these elements need to be available in balanced proportions for sustainable successful coral health and growth - This Test Kit Enables Accurate Dosing Of The Reef Foundation Supplements - Test Kit Includes 5Ppm 75-Test Calcium Pro, 0. 05 Me/L 75-Test KHz/Alkalinity Pro And 20 Ppm 60-Test Magnesium Pro Tests ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004FUJ5NE | | ASIN | B004FUJ5NE | | Age Range Description | all stages | | Best Sellers Rank | #124,327 in Pet Supplies ( See Top 100 in Pet Supplies ) #218 in Aquarium Test Kits | | Brand Name | Red Sea | | Country of Origin | United States | | Customer Reviews | 4.3 4.3 out of 5 stars (770) | | Date First Available | December 10, 2010 | | Date First Available | December 10, 2010 | | Department | unisex-adult | | Department | unisex-adult | | Directions | use as directed | | Included Components | all | | Is Discontinued By Manufacturer | No | | Item Dimensions LxWxH | 5.91 x 7.09 x 3.54 inches | | Item Package Dimensions L x W x H | 6.57 x 5.67 x 3.19 inches | | Item Weight | 16 ounces | | Item model number | 306027 | | Item model number | 306027 | | Manufacturer | TopDawg Pet Supply | | Manufacturer | TopDawg Pet Supply | | Material | cotton | | Model Name | Red Sea Reef Foundation Test Kit - Calcium, Alkalinity & Magnesium | | Number of Items | 1 | | Product Dimensions | 5.91 x 7.09 x 3.54 inches; 1 Pounds | | Size | 60 test | | Target Audience Keyword | dogs, fish, house-cats | ## Product Details - **Brand:** Red Sea - **Item Form:** Liquid - **Item Weight:** 16 ounces - **Liquid Volume:** 7 Liters - **Manufacturer:** TopDawg Pet Supply ## Images ![Red Sea Reef Foundation Pro Test Kit - Accurate Calcium, Alkalinity & Magnesium Testing for Saltwater Aquariums - 75 Tests, Easy-to-Use - Image 1](https://m.media-amazon.com/images/I/61zkpMiCmnL.jpg) ## Questions & Answers **Q: Recieved two bottles of A for the calcium test, how do I get a bottle of B?** A: Some people I swear, you got a bottle of A and a bottle of B. **Q: How accurate is this kit? Planning on switching from Salifert as I think this will reduce my costs some, seems easier to use with hand tool?** A: According to the kit, the Calcium is +/- 5ppm, KH is +/- 0.05 meg/l and the Mg is +/-20 PPM. Ive only had it a short time but I have found it to be accurate based on my tests. I have verified dKH was very close to my Hanna tester. I have only used 1 salifert kit and I can tell you the Titrator handle makes adding the titration fluid easy and quick. Overall it makes the tests much easier to perform. **Q: Is there a refill kit for these tests with just the Titrant’s and Reagent’s?** A: Not with the one I bought. But you can buy them with the refill kit or get them at Petco. **Q: by other reviews, do these kits still contain the recalled calcium reagant? These are the faulty batch numbers. Thanks** A: Stamped on the label of Calcium Reagent B, and compare it to the list of faulty batches: 1993, 2003, 2013, 2023, 2033, 2043, 2053, 2063, 2073, 2083, 2093, 2103, 2113, 2123, 2133.Those were the only batch's that were faulty. ## Customer Reviews ### ⭐⭐⭐⭐⭐ RED SEA REEF TEST KIT - VERy GOOD 100% Excelent *by N***C on July 20, 2013* RED SEA very good product.

I've been using salifert which has been consistent but when I dosed my alkalinity with the red sea I noticed it was .5 Lower than the salifert. I tested 3 times with the red sea and each time was 8.4. I think the red sea is probably more accurate.

I like both test kits but I think I prefer the red sea. ### ⭐⭐⭐⭐⭐ Red Sea and Me *by T***O on July 19, 2015* Red Sea has done a great job of packaging a test kit where you feel the product equals the cost. Let me explain. 1. The case is nice hard plastic 2. The titrator makes testing easy 3. Color coordination delineates between each test and reduces the likelihood of cross contamination. 4. Test equipment like containers are glass. Red Sea also has made testing clear and easy to complete. There are several utube videos that provide consise instruction along with manual and visual cards that make anyone comfortable using this test kit. Some advice for new users. 1. Clean clean clean you syringes and test containers with RO water( no soap) each and everytime you put away your kit and between each test. 2. Take your time and read instructions and watch videos until you have some confidence you know what you are doing. 3. Rinse each container in the salt water you are testing when you are ready to test. 4. Most IMPORTANT, take your time and measure each full drop. You dont want to push through too quickly and miss your color change. I recommend without reservation this test kit. Yes it is higher priced but for the difference you will be wishing you brought this kit first because you know you will trying to save money. The Titrator on its own makes testing that much easier. ## Frequently Bought Together - Red Sea Reef Foundation Test Kit - Calcium, Alkalinity & Magnesium - Red Sea Fish Pharm ARE21525 Marine Care Test Kit for Aquarium --- ## 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.hr/products/1627402-red-sea-reef-foundation-pro-test-kit-accurate-calcium-alkalinity](https://www.desertcart.hr/products/1627402-red-sea-reef-foundation-pro-test-kit-accurate-calcium-alkalinity) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-24*
