Ok but be careful By Grant on 12/5/2012

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 12/1/2012

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.

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 11/28/2012

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 11/28/2012

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.

Great product that is easy to use. Reliable phosphate tester and you wont have to guess have you phosphate really is.

I found it difficult to use when I first started. Once you get the hang of it, it will give you an accurate reading.

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 9/28/2012

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!
