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

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.

i love this product. it is very accurate and if you are running GFO it is a must. Make sure you add a few extra reagent packets to your order!

The Hanna Checker is simply the fastest and easiest way to check my reefs phosphate. I’ve been in the hobby for over 15 years. As a reefer who is also legally blind reading test kits and colors has always been hard… This actually made my reef keeping life simple again!

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

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.
Phosphate test, without a useless color to decipher By Keith on 9/7/12

I finally know what my phosphate is at, thanks to not having decipher a shade of blue, that looks diffrent to everyone that looks at it. Wish it came with more reagents but the refill kit is pretty cheap.
hassle to use due to manual dexterity By Join the Revolution on 9/6/12

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
Steven would recommend this product to a friend
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.
great By Chris on 9/1/12

I just got this the other night along with the calcium test kit from hanna. The alk is a lot easier to test for and the reading was up to par with my other test kits. Only time will tell
Accurate and FAST! By Damian on 8/31/12

I cannot tell the shades of blue apart on the regular phosphate test kits, so the checker was an easy choice when it was time to get a new test kit. You won't be disappointed if you like to track phosphate.
Love it! By BRIAN on 8/30/12

I absolutely love my Hanna PO4 checker. Being colorblind I no longer have to bother the wife to compare colors for me. It's very easy to use and has always provided me consistent results. I'll never go back to the old way of testing PO4 again.

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.
Good tester, need more reagents By Mark on 8/17/12

This is so much better than trying to figure out what shade of blue it is on a color chart.
My only complaint is that it only comes with 6 reagent packets.
Slight Learning Curve but good overall By Andre on 8/14/12

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.
Fell apart after 3 uses By Nathan on 8/3/12
Nathan wouldn't recommend this product to a friend
Don't get me wrong, this thing is easy to use and works great, but it fell apart after the 3rd use. The top detached from the base so now when I use it I have to try and hold the top on so it doesn't fall off. I have tried to contact Hanna about this issue two separate times and have received no response.
It works great and I understand you run into issues with products from time to time, but receiving no response from a manufacturer is unacceptable.

Extremely easy to use! Test kit is simple and accurate. I tested it versus my salifert and red sea kit and the test was on the mark I did not need to look at silly color charts. GREAT PRODUCT. Now if only hanna can make it for other parameters and fix their calcium checker.

Fantastic Checker, really acurate and easy to use. The money seams steep, but the acuracy and ease of use make this a great addition to your phosphate fighting arsinal.

just received the phosphate checker and was skeptical that a colorimeter could be produced for sucha low price. Tested it on three reef tanks and results were zero. Thought the unit was defective, so waited all weekend and tested it on a freshwater planted tank in office. Three minutes later .91 PPM. Like a charm.

The best consumer phosphate tester by far. By NanoCabana on 6/18/12
NanoCabana would recommend this product to a friend
This is an affordable and accurate tester for phosphates. Like many, I was tired of trying to match color shades on a card. With Hanna's digital readout, I have confidence that my weekly test can be compared for trends. I also use this for my planted freshwater tanks and will buy Hanna's iron checker in the near future. Good job Hanna!
