Royal Nature Phosphate Test Kits
Very similar to another well known brand but easier colour change reading and instructions.
Easy to use and accurate.
Royal Nature phosphate professional test kit is designed to be easy to use and read plus give you 100 tests per kit.
Royal Nature took the time to make this kit not only affordable but easier to read and more accurate. The biggest complaint on titration test kits is reading the colour shift to be accurate.
Since colour variation can be subject to many factors - ambient light, how you hold the sample, your own eyes, Royal Nature wanted to take the time to use analytic studies to make the colours brighter to the average eye.
The Royal Nature Phosphate Test Kit is a two-step process using an indicator and powder reagent. The test measures PO4 levels from 0.05, 0.1, 0.3, 0.5, 1, 3, and 5 ppm. Since PO4 levels in natural sea water is around 0.06 ppm, it was important for us to give hobbyists the ability to monitor it at a usable range.
