Hanna Phosphate Checker is good! By Diana in OK on 5/6/13
Diana in OK would recommend this product to a friend
Could use easier written instructions but if you watch the YouTube videos it's easy enough to do. Happy with my purchase of the phosphate checker by Hanna.
Be sure to order more reagents as the kit only comes with six packets.

No more "is that purple, wait in this light brown" takes the guess work out, great for typical reef with SPS, use to check your GFO depletion, check tank reading vs outlet of reactor when they become the same change it out, will pay for its self I promise ;)
AWESOME PRODUCT By Chris on 4/8/13

First be sure that you buy more reagents when you buy the kit, there are only 8 in the kit. This is a minor annoyance that you can rectify up front if you know!
Otherwise no complaints its a dream to use and the BEST for testing PO4. So easy to do, easy to read, so accurate, repeatable. helps me know when its time to change the GFO and keep Algae at bay!
You will not be disappointed with this product!
very nice and easy to use By Andy C on 4/8/13
Andy C would recommend this product to a friend
This is a very nice tool for checking phosphate. The only tweak I had ot make was to prepare the reagent vial before putting the water sample into the checker. Otherwise it'll time out while the reagent dissolves. Otherwise, this is great.

WAY Easier to then other kits, but a few quirks By tommyd193 on 2/21/13
tommyd193 would recommend this product to a friend
This kit is far better and way easier to know what your level is, I just wish I knew there were only 6 tests that came with the kit or I would have ordered more. As mentioned in other reviews getting the powder out of the packet is tricky and if you take too long then your unit shuts off on you, but once you master it and develop your own knack then it's well worth the purchase!
It gives a number. No guessing By Kevin on 2/19/13
Kevin would recommend this product to a friend
Tester is very good. I like it because it gives me a number instead of the color chart that the other tests uses. Only problem with the tester is the green cap can be broken away from the base part. I'm not a very hard handed person but my cap broke off on the first use of opening it. Not sure, the cap could have already been broken. But i have still used my tester i just snap the cap back on.
Just plain awesome By Nicholas on 2/19/13
Nicholas would recommend this product to a friend
This is the single best test equipment investment I've made thus far. My other phosphate kit was worthless compared to this.
The only thing I don't really like about this is the packets are a pain to empty into the test vial. why not just sell the reagent in a little container with a little spoon like others do?
Easy to use By Miles on 2/13/13
Miles would recommend this product to a friend
This test is incredibly easy to use, but has a down side. Getting all of the reagent out of the pouch and into the vial can sometimes prove tricky. check out the video on the Hanna Checker website to learn how to do it right. The process is very simple, just not super intuitive. Other wise this product is great, I use this in conjunction with GFO to keep my system free of phosphate.
Awesome product By Jeremy on 2/11/13

Much easier to use then trying to match colors on liquid tests, I deducted 1 star for the poor reagent package design, can be tricky to add if you rip the package open to much.

There is a learning curve By SCUBAFreaky on 1/30/13
SCUBAFreaky would recommend this product to a friend
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 1/24/13
Charles would recommend this product to a friend
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 1/3/13

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.

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 12/22/12
Ryan would recommend this product to a friend
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 12/22/12

Ok but be careful By Grant on 12/5/12
Grant would recommend this product to a friend
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 12/1/12

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 11/30/12
Old Salt would recommend this product to a friend
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 11/28/12
william would recommend this product to a friend
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 11/28/12
Andy would recommend this product to a friend
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.

Subodh would recommend this product to a friend
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.

hell i just got my hanna hi 713 today all excited to test phosphate.
so i open it and go step by step testing my water waiting on this high reading to show up because i have algae growing every where. well is shows 0.00 on test one I think well that cant be right so i test it again same deal 0.00 ok so i text my tap water 0.03
so there is 3 of my 6 test wasted imo, I know the tank has po4 i got this with a gof reactor to test weekly to me it dont seem to work
Easy enough By Edward on 9/29/12
Edward would recommend this product to a friend
There are two reasons I gave 4 stars instead of 5. First is that the syringe that is used to get the reagent does not always attach firmly to the tip supplied. As such, it can drip out and you have to push the tip on again. The second reason is that at the levels of phosphate I run (reef), I wish BFS carried the ULR phosphorous Hanna Checker. Even though it is not phosphate, you can calculate that by multiplying by about 3. That unit has more accuracy and can read a little lower. But I suppose the phosphate one cannot be faulted as it does what it is supposed to and is easy to use other than the tip on the syringe.

it is nice to be able to know for sure what your tanks levels are. for me there was a little bit of a learning curve and i used a lot of the reagent. you should buy extra reagent when you make your purchase. you do need to use caution opening the cap or you could break it.over all i am very pleased and glad i bought it.
Accurate, but... By james on 9/22/12
james wouldn't recommend this product to a friend
I absolutely loathe the reagent packets.
I wish it was a liquid reagent like the Hanna Alk, but unfortunately it is not. Instead (as another poster mentioned) you have to dump the contents of a small packet of powder into the hole of one of the test vials. It makes it a bit of a pain to work with.

Do not buy it. Go Salifert, or other means. This test would be a great if it was designed to work with ease. This test tries to be innovative ,but titration is much easier and guessing is eliminated. Who wants to pour a small pack of powder into a small hole the diameter of a dime???! The lid is difficult to open and the instructions are so 3rd world. Next..
Seems to work but cheaply made By Steven on 9/4/12

The meter seems to work fine, but be made of cheap plastic. The second or third time I snapped the lid open, it came off. It looks like there are only two small ultrasonic welds that hold the top part on. The meter still seems to work fine, but I have to keep pushing it back together every time I open the lid.

I have the low-range phosphate colorimeter.
Upon receiving, I opened the top of the unit and the entire top white part separated from rest of the body (the small plastic pins holding it sheared away)--a rather inauspicious start. It is still usable and I don't want to screw around with returning it--despite BRS and their excellent return policies.
I just have to hold the white part against the rest of the body and it works OK.
WATCH OUT for the regent. Use a scissors and OPEN CAREFULLY! This stuff has a very low PH and will irritate skin noticeably. In addition, the reagent is a little tricky to pour out of the envelope which can increase risk for accidental spillage. Again, use care with this reagent.
Other than questionable quality or quality control of the physical unit and the nasty reagent, I cannot possibly imagine living without this essential instrument.

What an awesome product! LOVE this tester. By Chuck on 8/13/12
Chuck would recommend this product to a friend
For anyone's who's used the 'other' phosphate testing kits, we all know how crazy-difficult it is to read which super-duper light shade of blue the result is to get a phosphate reading -- basically inaccurate/impossible and something I stopped doing often because it was a waste of time. NO MORE! After getting the Hanna phosphate checker, it completely takes the guess work (and eye-straining) out of phosphate testing. I almost feel spoiled having the digital read-out of the phos level after struggling with other test kits for years. This is one of the best and easiest tools, along with a nice refractometer, that I have for my 240g mixed reef. And with this low of a price tag, it's a no-brainer that every aquarium owner should have one.
