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 9/28/2012

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 9/22/2012

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 9/7/2012

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 9/6/2012

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 9/4/2012

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 9/1/2012

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

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.

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.
