Rated 5 out of 5 by RMax5650 Easy to use, accurate.
This product is easy to use even though there are several steps. The only problem I encountered was that you had to be under a strong overhead light in order to achieve a color in the test vial that matched the color chart.

Rated 5 out of 5 by civicman very nice quality
Let me start by saying the quality on this is better than the common, cheaper liquid test kits out there (you know the brand). I always suspected my tap water had phosphates in it; the more I would do water changes, the more the algae would seem to grow. Sure enough, my tap has about 1 ppm of phosphates (kinda high), but my tank tests close to zero (phosphate reducing media). The test is fairly easy to do, and the test Vial is plastic but actually really nice and wide with a secure cap. The color chart while not fantastic, served its purpose and the color match is pretty good (different degrees of white to blue). It was close enough for me to feel like I was not really guessing on the color. It's worth the extra money to get this test, however while Foster/Smith prices are VERY competitive, the MSRP price is still a bit high. Thanks docs!

Rated 5 out of 5 by ReefFan Good Phoshate test kit
I like this Phosphate kit. It is easy to use and accurate. It is very important in a reef aquarium to have Phosphates as low as possible. If they are high, you wont have success keeping corals alive or colorful. This test takes about 3 minutes to perform. There are only just a couple of steps but it is worth checking. I use this at least once a week.
