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.

Great Tool but can be wasteful By Europhyllia on 3/18/11

I like this checker. It works well. But I wish I could change the setting on the auto-shut off to last longer than 10 seconds.
It takes 3 minute to process. If I get side tracked and pay attention to something else I miss the 10 seconds in which the result is displayed. Then I have to use up another reagent package and start all over.

Make reading phosphate much easier By Larry on 3/6/11

Always had trouble reading those color based checkers. This test kit defintely takes out most of the guesswork. Still takes some work to check but at least you know you are getting a good reading! One downside - buying all the refills could get pricey after a while.

Never Guess a shade of blue again By Tina on 2/19/11

Great little meter. Do read through the instructions first to get use to the symbols on the screen and the timing. You don't have a lot of time (but it's enough) and you will get use to it. Do buy an extra set of test reagents. The test is so much easier to perform you will actual do it so those first 6 test won't last that long.
I actually store one of the tubes inside the checker to make extra room in the case.

If I had any downside I would say the clasp on the case seems a little cheap, I think over time it might have issues. But none yet.

So easy to use! By June on 2/19/11

Purchased this along with the HC GFO. Will NEVER go back to a color chart test kit. When we used our other test kits for PO4, we had to walk through the house trying to get good light for an accurate reading. Now, all I have to do is read the meter while sitting at the table. Super easy to use. Makes me want to test more often since it's so easy. Also purchased the additional packets of reagent since this kit only comes with 6. A++

A great tester for the money. You do have to pay attention or you'll miss it. But once you get the hang of it, its easy. I would definately recommend it.

I love this thing! By Bob K. on 1/12/11

I've been struggling with Po4 test kits since I've been reefing. This makes it easy. It costs about the same as two high end test kits but the precision and readability of the results makes it worth every dime.

It works well and easy to use. Get the extra reagents you will want them down the road. Make sure you are watching it when its done as the reading only stays around for a short bit.

A step in the righ direction By John on 9/27/10

I have always hated test phosphates. I am color bind and have trouble comparing the slight shades of most test kits. This product solves my problem. Its well made and simple to use.

My only complaint is that it only comes with enough powder to do 6 tests. Otherwise, it's worth it.

Hope they make other testers. By J_T on 9/16/10

This makes testing for Phos simple. The other test kits make it a guessing game. There is no guessing here. Follow the simple instructions, and there you have it.

I use both tubes, one for calibration, then the second has the reagent mixed in.

The only down side, that I hope they address for future kits, would be that you only have a few seconds to see the results, and then their gone.

If your buying this, also grab a refill of the reagent. 6 packets won't last as long as you think. Given how easy the test is to preform, you will find yourself actually doing them!

worth it By Jim on 9/10/10

I was following BRS’s recommendation to change the material when I started seeing algae growth or had to clean my glass more often than normal. This worked pretty well but the checker is a pretty big upgrade from that. Now I can change it before I start to see more algae growth. The checker also allows me to use the GFO to max capacity and I am sure will save me money over the long run.

Easier to read than others By Mike R. on 8/28/10

I purchased this tester to test the phosphates. I was using a Salifert kit, but like most test kits, there is a lot of judgment and room for error when reading.

The Hanna kit is easy to use. It is is simple as filling a tube, inserting it to calibrate, taking the tube out, put the powder in, then insert again. 3 minutes later it gives results. It has its own timer so counts down the 3 minutes for you.

An additional comment is it comes with a handful of powder to test, so if you want to test daily for more than a week, you may want to get extra powder.
