Its one of the easiest test kits I have used. It takes 3 minutes and you have a perfect reading. I have used manual test kits but this one can be done over and over with the exact same results.

Not as accurate as the HI-376 By Steve on 12/26/11
Steve wouldn't recommend this product to a friend
I wish I had done a bit more research about this before buying it. This Hanna model (HI-713) has an accuracy of +/- .04ppm when target levels for phosphate are usually considered < .02ppm. I would much rather have purchased the HI-736 Phosphorus Ultra Low Range Tester by Hanna. Too bad BRS doesn't stock both and explain clearly the difference between the two.

I've had this for about a year, but only used it about 20 times. It broke due to a manufacturing defect. The Hanna customer service would not stand behind their product. Despite the defect, they indicated warranty was only 6 months and they wouldn't do anything.
Fantastic By Brian on 12/20/11

Fantastic product, no more trying to compare colors with those horrible color cards. The only down side is the powder reagent, hopefully Hanna will develop a liquid reagent.

The Hanna Checker Phosphate PO4 Colorimeter is very easy to use and only takes a few minutes to make sure that your tank is where it needs to be! I have spent so much money on frags, fish and equipment - the cost of this item is well worth it! Make sure to add the extra packets to sve yourself from running out.
I plan on getting the other Hanna checkers for my tank

I wish I purchased this product before wasting my money on impossible to read color tests. Well worth the money. Best upgrade I've made to date

This is soooooo much better! I really like the digital readout. The test instructions are very easy to follow.
Be careful opening the test unit for battery installation, make sure to pull the battery door out straight and do not pry it to one side.
Hanna Checker Phosphate PO4 Colorimeter By Virgil on 11/27/11

Loved this tester. No more other test for me. The digital read out makes it soo much easier. I'm getting the calcium checker for Christmas I liked this one soo much. Thanks for providing a great product. Just read the instructions and maybe review a youtube video on using it. The system has a timeout and you need to complete all the actions within a certain amount of time, but there is enough time if you are prepared.

Extremely easy to use and amazingly accurate. Absolute must for phosphate control, great to check your top-off water.
