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.

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!

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.

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.

This meter is great. It takes a bit of practice to get all of the reagent into the sample but it's much better than training to match to colors by eye.
Makes testing easy By Justin on 12/10/2014

I bought this cause I used other test in the past and can't get a good reading. 0.0 - .25 how can u tell exactly what your levels are at. I'll tell u Hanna checkers. Gives u a digital readout I love that. I have the phosphate and alkalinity tester. Works great. The only down fall is buying the test solution. It's a pain to have to order it and for 10$ for 25 kits it's not the cheapest test kit. But I wouldn't use a different test again.

Bought this tester to help dial in biopellet reactor. The test results seem accurate. But with multiple test obviously required to know what's going on with the biopellets the few test packets included didn't last long at all.getting the powder out of the packet and into the test vile seems challenging. Would have preferred a bottle of powder and small scoop like every other quality test kit has.

I so glad I have an easy way to test for phosphate. I hated having to run from room to room trying to find the right light to analyze results and even then not knowing if I was interpreting the result correctly. I don't have the problems others have mentioned with adding the reagent, you just need a steady hand. I will order all the others in time.

Received it, and with it being the first time I've used this type of product, the instructions weren't overly clear, so I used 2 packets of powder to test...both tests came up at 0.00. Odd since it's pukani rock. Played another time, and got my reading that was right.
Product works great now. Wish they gave you more than 6 packets of powder though.

A good test kit! By Brandon on 9/15/2014
Brandon would recommend this product to a friend
I love the digital output on this test kit. My only concern the possibility of human error that can throw off results. I say this because the reagent comes as a powder form and it comes in its own little packets. I don't really like the packets because it is impossible to get all of the reagent from the packet into the test vial unless you open it up and scrape it with a blade. I would have rather seen a container with a measuring spoon like the on in Red Sea's Calcium test kit. Other then that I do really like this test kit and I would recommend it.

Accurate measurements, and includes a storage container for everything along with a laminated instruction card. It is a chore to get all the powder into the vial for the test. Work fast, or do some prep work beforehand. Several times I thought I got all the powder only to find that there was still a bit more in the packet. Take your time, get all the powder into the vial first and then calibrate. It includes 6 reagents so add those to the cart as well.

if you have hair algae, you have phosphates....period. No matter what i used I kept saying to myself "my kits show no phosphates. I had to give in and get this Hanna Checker and it was the best move ever. Combined with my GFO reactor and I had a happy tank in no time. I wish the kit had more reagents, but if i had a controlled tank I wouldn't have had to check so many times :). Great product but be very careful with the vials to ensure they are CLEAN and scratch free prior to running your tests. It could skew the results.

I have no issue with the checker or its accuracy (it works great) the only issue I had was that it only came with 6 reagents. for those that like to test on a regular basis I suggest you buy some with the initial order. besides that its awesome.

Works Great! My husband was actually excited when he DID get a phosphate reading with this test kit. Would like to suggest BRS add a suggested link to the refill reagent packets to buy with it so the customer can save a little on shipping as there are not that many reagent packets with this kit. Wish I had ordered the refills with it. Other than that, it is well worth it and I would recommend it highly to anyone who owns a tank.

I love how easy this is to use! I've used many different test kits but this is the easiest by far. My only worry is that I hadn't run gfo in a few weeks when I received my phosphate checker and it still read 000? It wasn't blinking so it wasn't a error reading? I tested 3 times the first night just to be sure because I thought I'd get some kind of reading?
Easy to use, but be quick By Paul on 5/9/2014
Paul would recommend this product to a friend
This meter is easy to use and you don't have to worry about figuring out which shade of blue you have against a chart. I have yet to run multiple test on the same water to check consistency, so I can't say anything to that effect. Only issue that prevented me from giving it 5 stars is the timeout. It will turn itself off after 3 minutes or so (to save battery) However when you do the first calibration, and then go to mix the reagent, if you get side tracked it will shut off and you'll miss the opportunity to run the test and have to start over. On occasion I ran the test all the way through, but got sidetracked waiting for the 3 minutes of testing and when i went to go check the result, it shut off. If using this product, I highly recommend not doing anything else to avoid the timeout.

I've had many phosphate test and matching colors is always hit or miss. Having a true digital reading is great . As people have said use both vials -makes the testing much easier. The packets are a bit of a pain- you have to be careful when cutting and adding them into the vial. Overall, I feel this is the best phosphate tester for the money

Nice little gadget. 10 times easier to use than a normal test kit. The only two problems are: is extremely difficult to get the reagents into the test tube, and sometimes the automatic display shut off can ruin a test by exiting before you can see the results.

Easy and Precise measurement By GUnit on 4/3/2014
GUnit would recommend this product to a friend
This is the easiest and quickest test kit for phosphate that I've used. I'm a sucker for precision and not having to guess at colors so this test kit is ideal for that.
The couple of recommendations that I would have for people buying/using this test kit are:
1) When doing the test use BOTH vials. This is key to avoid having the meter turn off on you while you combine the reagent with the sample (2 minute shake time vs 2 minute auto shutoff.... :( ) Fill both with the appropriate amount of sample. Set one aside with the cap on. Add the reagent to the second and begin the 2 minutes mix/shake. About half way into the shake drop the first non-reagent sample into the meter and calibrate. After you're done shake drop the vial with reagent in an get a reading!
2) Buy more reagent immediately (or shortly thereafter) as you only get 10ish reagent packets in the kit.
