costly By jeffrey on 10/4/11

it is costly, but i am glad i got it, it is very acurate, and easy to use once you manage to dump the packet in the cuvature.

Excellent Product! By Reefer on 10/1/11

I've been using this product for a few months and the only thing I could suggest is that Hanna make a liquid reagent available. Accuracy is right on with Salifert test kit.

Finally something easy By Brady on 9/29/11

This is a huge step up from trying to read different shades of a color. I just can't wait till they bring out other testers

More accurate way of testing By Don on 9/29/11

This unit is as close to lab results as you can get. Just 2 simple steps and wait the 3 minutes for the results. Much easier than matching a color to a card.

good product By Craig on 9/22/11

I totally like having a digital read out instead of try to match colors like the other test kits, but the Hanna Checker is a little hard to use. You have to be able to open a packet with a wide opening and pour it into a very small hole, in a short amount of time. It comes with two curvettes so I started using one for the "zero" and the other for the phos reading. I still don't like the packets though, it's hard to empty all the contents without spilling reagent powder.

5 stars! By Jeff on 9/21/11

The Hanna Phosphate Checker is a great product that makes testing phosphate so easy and accurate. I tested the unit against another more expensive product and it was spot on in three different tanks. Can't wait to get my Calcium checker and then the Alkalinity...I hear they are also releasing a Magnesium checker as well.

This was the first hanna I tried. I now want every hanna test kit that is available. This thing is super easy and gives you such a pin point reading, no more guessing!

No faster than adding drops, but not having to guestimate or ask my wife what color is the match is far nicer.

easy to use and accurate By Chris on 9/3/11

It's Great By Grey on 8/24/11

Grey would recommend this product to a friend

Finally able to check something without mixing a bunch of chemicals. It's easy to use, and accurate. What more do you need? The only problem I had with my tester was that the tester flip top lid is very tight and difficult to open without using your fingernails, but I am sure it will loosen over time. I am just thrilled that about not having to pay 40 to 70 dollars for 25 liquid chemical phosphate laboratories anymore.

Great Product! By Chad on 8/24/11

I bought this to keep my Phosphates in check since color card tests are inaccurate and VERY hard to read. I must say that I am impressed with the accuracy! Several tests on the same water sample resulted in the same numbers over and over.

My only real problems with the unit is the lid is VERY hard to open. If you have short fingernails or arthritis you make have problems getting the lid open. Another other problem is the reagents. I really wish they were in liquid form, it is hard to pour the dry powder in the tiny opening of the vial.

Finally the automatic shutoff timer of 2 minutes between C1 and C2 is much too fast! The powder does not dissolve quickly enough and you risk ruining the test if the unit times out. A more lengthy time period is needed here if dry powder reagents are going to continue to be used.

Other than these small problems the Hanna Phosphate Checker is genius!

Best phospate testing period By Richard on 7/30/11

Richard would recommend this product to a friend

There is no other way to go. My local reef store recommend the Hanna, I ordered it, and there is no going back. Just be sure to follow instructions on keeping cuvettes clean, unscratched, and not introducing bubbles when testing. Standard test kits cannot be relied on, the Hanna is the way to go.

Love it. By Rick on 7/30/11

This is easily the best piece of testing equipment I've bought in years, accurate to three decimals. 0.015 target.

Hard to know how accurate the measurement By Joe on 6/24/11

Joe wouldn't recommend this product to a friend

This one is hard to know how accurate its measurement really is. I got different results even with same water sample. And of course that 3 min. timeout is crazy, lost a few package because of that.

Way too easy! By Jonathan on 6/15/11

Im so glad they finally came out with these kits! I hate checking my params but now its almost fun!Easy to read and fast as lightning.A+ all the way

much more accurate By Gary on 5/25/11

Gary would recommend this product to a friend

phosphate test kit read 0 phosphates (too little color to see), but i still had some microalgae growing on the glass i had to clean off every few days. Switched to Hanna, i actually had .08 phosphate. Now i'm down below .02 on the Hanna, no more microalgae on the glass. Results speak for themselves, i'll never go back.

I have a tough time reading tests with color chips. This instrument makes testing quick and easy.
