If you have not seen this video by @Bulk Reef Supply then we highly recommend Checking it out. @Ryanbrs and the BRStv team take a look at our HI713 Low Range Phosphate Checker and HI736 Ultra Low Range Phosphorus Checker to see which one is better for your reef tank. Make sure to watch the video below! For a further explanation of these two Checkers, why we use that conversion and which Checker is right for you, please see our thread in Reef2Reef. Make sure to download our phosphorus ppb to phosphate ppm conversion table attached.
