Good Po4 Test Kit
I like these Red Sea test kits they come in a nice container and simple instruction cards. This one requires you to fill 2 vials and simply turn the cod until both match and gives you the reading. I have and am finding this product easy to use and accurate. I would recommend this for testing phosphate.
