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!

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

What could be simpler. love this, have both the phospate and alkalinity checkers and my testing has become so much easier.

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

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.
More accurate and easier to read! By Dave on 6/16/11

Since purchasing this checker I no longer need to ask my girlfriend to help match the colors of the test kit. My salifert test reads 0 when this reads .02-.04, which explains the slight algae problem I still have.
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

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.
Simplify your life go digital By Robert on 4/12/11

This has been one of my best moves yet. Takes all of the guess work out of the equation. 3 minutes and your done. LCD shows you clear and easy to read results with ample amount of time before the unit shuts off.
One thing though when you mix your reagent you gotta be quick you only have about 1 1/2 minutes to do so and set the checker. I find that shaking the vial vigorously and then slowly rotating it from left to right to remove the fine bubbles gives you enough time to get the vial in the checker and set the timer. I will be purchasing more Hanna checkers in the near future.
Great Tester - The devil is in the details By Nick on 4/9/11

This has been a giant step up from the old testing methods I have used in the past. I have never liked the color charts and the math involved. When I see a chance to go digital I am normally first in line to give it a shot. I don't think the instructions or simplicity of the colorimeter could be any better! The only problem I have with the system is actually getting the reagent in the vile. I have wasted 2 packets so far due to not all of the powder making it in. After that I wised up and purchased a small funnel (one to put fluid in a flask) and it has been smooth sailing from there on.
