Well, I've already described it, which should work for most people. Not really all that difficult....
But if you want videos, BRS has made a couple. First one is about phosphates in general and how to test for them. The second one is about choosing the right test kit, and shows how to use them. The Hanna phosphate checker part is near the end of that one. The only diff with my method is that I swirl for close to 3 min, not 30 sec to be sure all the powder gets dissolved. http://www.bulkreefsupply.com/video/...ing-phosphate/
