There is a learning curve By SCUBAFreaky on 1/30/2013

This is by far the best test kit for measuring Phosphate, but there is a learning curve. As other posters have said there is an art to getting all of the powder in the curvette, but once you get the hang of it, it's no longer an issue. Also this thing will time out after 2 minutes during the phase when you are dissolving the powder. Once it times out, you pretty much have to start over due to the baseline scan. Also be aware that it only comes with 6 reagent packets...and you'll blow through those very quickly due to the learning curve. Unlike other posters, I'm having trouble getting consistent measurements, but all that said, the Hanna Checker is best phosphate checker I've used so far.
Works Great and Easy to use if you open the package on two sides By Charles on 1/24/2013

Just cut two sides off of the regents package and them trim the corner off at the tip, open and pours in with ease.
Do this before you put the water in the machine andit won't time out.
GREAT By Samuel on 1/3/2013

I was using Salifert test kit and I could never get a accurate reading. Now with this Checker I have a way better idea as to what my phosphate levels are.
I gave it 4 stars because it is a little hard to get the powder in the vial the first time but after some practice its no biggie.
PHOS-tastic!! By shaungee on 12/28/2012

Picked this up on a black Friday doorbuster deal, and couldn't be happier. There was a little learning to be done on how to use the device, but once that was done, I can quickly and confidently test my levels in my tank and make necessary adjustment. Also BRS came through on shipping with a 2 day turnaround, Amazing!
Consistent and accurate!! By Ryan on 12/22/2012

Consistent and accurate!! If you are keeping corals you should get this. The test kit that I have been using always tests way lower than the hanna checker so I've always thought my phosphates were more in check than they were. Now that I know where my phosphates actually are. I have been able to get them more under control and have noticed an increase in coral growth already.
Thank goodness By Joseph on 12/22/2012

Phosphates fianlly easy to check. I love all 4 that I use. Just waiting for the nitrae checker to come out or even better an all in one.
Awesome By Chad on 12/15/2012

Hanna Checkers are downright awesome. Accurate, digital, takes less than five minutes. They are the best meters I have every used.
Ok but be careful By Grant on 12/5/2012

In the instructions it says after adding the reagent to shake for 2 minutes. But the colorimeter turns off after 2 minutes. So I have wasted 2 of the reagent packets out of the few that come with it and have yet to accurately test my water.
Obviously a user error but just a tip.
definately worth the purchase By DANIEL on 12/1/2012

Love the precision of the digital readout. No more guessing color shades. 5 stars. Minor item(s) - only 6 tests provided with kit. Also, small amount of effort to learn how to pop off plastic lid cleanly.
Check it, mate By Old Salt on 11/30/2012

Well worth the investment and once you get the hang of dumping in the powder--can be dicey at first--it's very easy to use. You do have to keep buying the reagent, but I use my checker sparingly, mainly to check up on an API kit that I use 2-3 times a week. The combination allows me to keep a close eye on phosphates.
Great Product By william on 11/28/2012

I currently have the Calcium, ALK, and Phosphate checkers, and they make testing the water amazingly easy. I was using ELOS kits before hand and these take 1/2 the time the others do. I still test with elos bi-monthly to ensure the Hanna's are still reading correctly. Wish they had more regents with the initial purchase.
OK but hard to use properly By Andy on 11/28/2012

I only recommend this because the alternatives are horrible or a lot more money. It is very hard to get all of the powder reagent out of the package, and opening the package properly and actually getting the powder in the vial is an art unto itself. This part will take you a few minutes alone. Then the joy begins when you try to get the powder to actually dissolve, and then stop bubbles on the cuvette. If you don't get it dissolved or free from bubbles, the results will be wildly off. I tested the same water with bubbles on the glass and without. With bubbles it was saying the phosphate was 5ppm! Without bubbles, 0.01ppm.
