Many aquarists have reported that a low potassium value reduces colors in corals. This can be corrected by increasing the potassium value to the normal natural concentration. Now you can accurately measure this value with the new Salifert Potassium Reef Test kits. Review: salifert is great - easy to use and accuracy is good enough for your reef tank Review: It works!!! - I recommended this for a friend who is on a low-potassium (K) diet. I figured that if it worked for aquarium water it would work for water that boiled potatoes, which have a high K content. After one boil in a full pot of water the K level of the boiled water was high. But after three boils the K level in the boiled was significantly lower. (Boiling is recommended by doctors for lowering K content.) This test helps her to know if boiling or other water-soak methods to lower K in food will help her decision on her diet. Still, I recommended that she not gorge on boiled potatoes but only eat a small amount to satisfy a craving. ## Features - Fast, easy, and accurate - Measures potassium from concentrations of 250 ppm to 470 ppm - Sufficient for up to 40 tests - For marine use only - Made in Holland ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0084CO4LC | | ASIN | B0084CO4LC | | Age Range Description | All Stages | | Best Sellers Rank | #73,584 in Pet Supplies ( See Top 100 in Pet Supplies ) #112 in Aquarium Test Kits #682 in Aquarium Water Treatments | | Brand Name | Salifert | | Color | Clear | | Country of Origin | Netherlands | | Customer Reviews | 4.2 4.2 out of 5 stars (128) | | Date First Available | December 21, 2012 | | Date First Available | December 21, 2012 | | Directions | Please see packaging for directions. | | Included Components | See packaging | | Is Discontinued By Manufacturer | No | | Item Dimensions LxWxH | 4.3 x 2 x 5 inches | | Item Package Dimensions L x W x H | 4.33 x 3.43 x 1.77 inches | | Item Weight | 3.2 ounces | | Item model number | RTKA | | Item model number | RTKA | | Manufacturer | Royal Aquatic LLC | | Manufacturer | Royal Aquatic LLC | | Model Name | Potassium Test Kit | | Number of Items | 1 | | Product Dimensions | 4.3 x 2 x 5 inches; 3.21 ounces | | Size | 7 Piece Set | | Specific Uses for Product | Water Testing | | Target Audience Keyword | Fish | ## Images ![Salifert RTKA Potassium Test Kit - Image 1](https://m.media-amazon.com/images/I/71BleRDgHNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ salifert is great *by A***R on April 6, 2024* easy to use and accuracy is good enough for your reef tank ### ⭐⭐⭐⭐⭐ It works!!! *by A***Y on November 18, 2018* I recommended this for a friend who is on a low-potassium (K) diet.
