Ideal for reef tanks and marine biology, it offers easy operation, reliable accuracy, and portability to help maintain optimal water chemistry and promote healthy coral growth. ## Description The HI774 is a cost-effective way to measure phosphate in marine systems, including reef tanks. Testing for phosphates is standard practice for saltwater aquariums and provides valuable insight into your reef tank's water chemistry to help ensure long-term coral health. Phosphates are one of the many forms of phosphorus compounds found in marine waters. Excessive phosphate levels can prevent calcification, skeletal formation, and growth of many coral species, particularly those referred to as SPS or small-polyp stony. In addition, high phosphate levels can cause nuisance algae growth in your reef tank. This can become problematic because algae often outcompetes sessile organisms for light, nutrients, and space, jeopardizing long term coral health in your reef.

As new salt water enthusiast it was important to get a tester that was reliable and accurate. ### ⭐⭐⭐⭐⭐ Accurate reading *by M***. on December 29, 2025* Good device that gives very accurate reading. Good packing and quick arrival ### ⭐⭐⭐⭐⭐ Seems to Work Well *by A***M on January 21, 2026* I use this frequently between my display and two quarantine tanks. I haven’t had another tester to compare its accuracy against but it seems to work. Pretty easy to use, just need to make sure to use a microfiber towel to wipe off the tube before placing it in, and that you get all the reagent in the small tube opening. Cutting a small corner of the packet helps. ## Frequently Bought Together - WLR Industries Hanna HI774 Phosphate Ultra Low Range Colorimeter for Marine and Saltwater appllications Phosphate checker - Hanna Instruments High Range Nitrate Checker HI782 - WLR Industries Hanna HI772 checker Saltwater Aquarium Alkalinity Colorimeter Checker Tester --- ## 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.vn/products/640928908-wlr-industries-hanna-hi774-phosphate-ultra-low-range-colorimeter-marine](https://www.desertcart.vn/products/640928908-wlr-industries-hanna-hi774-phosphate-ultra-low-range-colorimeter-marine) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-03*
