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.

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.

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.

I found it difficult to use when I first started. Once you get the hang of it, it will give you an accurate reading.

ok, I'm assuming everyone did their homework and the numbers shown by this thing are perfect and tested.
Just kidding, I cross-checked with the Red Sea kit. Hanna showed me 0.13 and red Sea Phosphate check came up between 0 and .25 Close enough for me.
I did take the one star off because - how the heck is one supposed to get all the darn powder from that pouch into the vial with that tiny a hole? I'll tell you how but not before I had to rack my brains. Get a clean sheet of A4 size paper, tear open the sachet, drop everything onto the paper, now lift it up and make a cone shape, drop the powder into the vial.
I almost took off another point for packing just 6 sachets. But well, it works well, instructions are clear and concise and no more asking the wife to read the damn colors. I guess I'll try the other Hannah checkers as well.
