Like others said, the packet is awkward. I got around that by after cutting the top of the foil off, I pry open the top of the packet with sissors until it creates a point, then carefully tap the foil on the edge of the vial until all the powder falls in. I do, however, have a lot to say about the calcium test...

it is a good product and accurate but beware the packets of powder are really difficult to get into the tube. other than that good product.
Hanna- do right to your customers and fix the packet!!! By Mrod on 6/27/2015

Hanna needs to redesign their packet design. If you like stress and frustration this is for you. Bottom line the packet design is a joke that outweighs anything else that is positive.

This is the first Phosphate test kit I have owned. Simple to use but as others have stated getting the powder out of the package is very tedious and not sure how accurate the reading is if the exact amount is not added...

I used this tester for the first time yesterday , and was surprised how easy and accurate it was. Testing water can already be a long dreaded task, but this hannah checker makes it a snap!, and its accuracy was great as well
Good Investment By Pipe Doctor on 5/16/2015

This device takes the guesswork out of trying to associate a color shade with a number, however, the test cover does not fully close and they only give you 6-7 reagents for testing. So out of the box you (1) have to hold down the top cover when a vial is inside and (2) limited to only 6-7 tests before you need to buy more.
Small Complaints By Stephen on 5/6/2015

It seems to test well but the tester lid doesn't always snap closed properly. Also the packets of test powder are a little hard to get the powder out easily.
Good tester By Russell on 5/4/2015
Russell would recommend this product to a friend
This tester is so much handier than the API test. It gives you an actual number instead of guessing at a color. It is also way more sensitive than the API tests. The downside is trying to get all of that reagent from the packet into that little vial without spilling it all over the place AND doing it within the time given. If it takes you too long, you have to start over. All around, a good device with a couple of quirks.
Too inaccurate for reef tanks By Adam on 3/30/2015
Adam wouldn't recommend this product to a friend
This is a quality, easy to read test kit for phosphates, perfect for fish only or less-demanding reef tanks, but I wouldn't recommend buying this one for most reefers. The accuracy is only +/- 0.04 so if you're trying to maintain phosphates between 0.01 and 0.03 ppm then this kit is useless.
The ultra low range checker works on a parts per billion scale, which is probably more appropriate for the typical reef tank. It reads between 0 and 200 ppb, which is 0 and 0.2 ppm.
Oh, and I agree with everyone else who doesn't like the reagent packets.
Finger acrobatics with tiny sachet-like reagents By Join the Revolution on 3/29/2015
Join the Revolution wouldn't recommend this product to a friend
Seriously? I bought this and used it about 2 or 3 times. The process of placing this tiny bag of powder into a tiny vial is ridiculous- regardless if it is accurate or not, it is poor product development. Don't believe me? Buy and try it. Not for me, next.

the best phosphate test its easy and fast just remember BUY EXTRA CHARGES because it come with just like 5 thats why i put 4 of 5 stars i would prefer pay extra but dont have the need to make a extra purchase some weeks after i get it
Quality Product and easy to use By Jeff on 3/26/2015
Jeff would recommend this product to a friend
The phosphate reagent package is what keeps me from giving it 5 stars. Took a couple of tests to get it down. I use both vials one for the benchmark and the other for mixing the reagent. I use a small square of notebook paper fold it to make a crease to funnel in bottle. That way i can shake all the reagent out of packet and have an easier way to slide the powder into the vial. Beyond that the testing is easy.
The only phosphate tester you should use By Nick on 3/22/2015
Nick would recommend this product to a friend
I have basically no algae in my tank, but I wanted to make sure and get accurate results as to what my phosphate levels were versus using liquid tests which are not always the most reliable. Little did I know that according to the Hannah checker, I have zero phosphate. There is a margin of error of +\- 0.04 but even 0.04 is still very good. Very happy with the purchase.
I wish hanna made a magnesium checker!

Easy to use, accurate. Purchased to extend the length of time between GFO change out. Should pay for itself over time as I was changing GFO on a schedule and it appears I was changing out too often.

This is exactly as advertised. I will not go back to my old way of testing phosphate. My only gripe is the titrant used. It comes in these tiny bags which are difficult to put into the test tube. I would give it 4.5 stars, but I have to round down for this one.

Extremely accurate, no more color guessing. By Brian on 2/2/2015
Brian would recommend this product to a friend
Well built, and easy to use. I only have a couple caviars; if you follow the instructions the unit will turn off while you are mixing the reagent. I recommend mixing it while using the second included vial to zero the checker. It only comes with 6 reagent packs, so be sure to order more. Also when opening the battery door, be careful to pry it straight away, do not pry it off at an angle, you will bend the connected pieces.
Just short of great By ONAP on 1/19/2015
ONAP would recommend this product to a friend
I really love the idea of this test meter, but the execution needs a little help. For the most part, it's great. Love the design. Easy to use. No guessing at colors, unlike other test kits. The only real issues that I have with this tester are the limited number of reagent packets provided with a new test kit, and the reagent mixing time. The instructions tell you to shake the vial for 2 minutes after adding the reagent. The problem is that the meter shuts off after two minutes. Another sixty seconds and a few more reagent packets, and this would be a five star product.

I like this test kit. For less than $50, I find it to be a bargain. Its easy to use and doesn't take long (about 5 minutes total). It's an important tester to have if you have a reef tank.

Simple and accurate. By DivingTheWorld on 12/19/2014
DivingTheWorld would recommend this product to a friend
This is a very simple and accurate test for phosphate.
The one thing I will say though is that you need to use both test vials at the same time. The instructions talk about going through the test , then adding the powder, then shaking it up, then putting the vial back in. The shaking/mixing takes 2 minutes and the checker turns itself off during that time... So I fill both at the same time, add the powder to one, shake it up, then run through the test.
Works perfectly this way with very accurate results.

It's extremely hard to gauge phosphates with other tests because you're trying to pinpoint color differences with the naked eye. This gadget does all the hard work for you in minutes!!! Amen
