Hanna High Range Phosphate Colorimeter

[Art]

My vote for best phosphate test kit is the Hanna High Range Phosphate Colorimeter. It's the HC H1717.

It measures 0 - 30 ppm with an accuracy of +- 1 ppm. The resolution is .1 ppm so just fine for what we need.

I like it because it removes my eyeballs and my shaky hands from the equation. I can follow the same procedure every time and get a reasonably accurate result, in digital form. This really helped me to track my ADA AquaSoil's PO4 sink ability and diagnose why I was getting algae.

While it is relatively expensive at $63.95 currently, you get what you pay for, IMO. It does go on sale at different places from time to time. I bought mine during the Black Friday sales.

Hanna is a testing company that really supports their products with science. They are also relatively quick to address issues as they recently did with their saltwater magnesium tester.

I highly recommend it.

I was just looking at purchasing this but with it stating it is a marine tester, I asked Hanna customer service about it's applicability to Freshwater aquariums and they stated it would not work accurately for freshwater applications.

Contrary to their assumptions(which may just be because of slight variability making them not want to state it works flawlessly for the freshwater application), I assume this is currently being used for freshwater testing and gives a good measure of Phosphates for us freshwater people?

That's interesting. I had called them up in the past and they said it was accurate for freshwater. Even their instructions say it is suitable for drinking water. I assume people don't drink saltwater.

Perhaps the person you spoke to was thinking about their low-range tests?

I would assume that if its good for drinking water its good for our tanks. I believe they are trying to push their Nitrate Photometer which is over $300 which does not state for saltwater use. I also find it odd because if you can use a Salifert or Nyos test, which are made and marketed for the saltwater community, on freshwater and get accurate results, why wouldn't Hanna's be accurate?

I am going to assume they work because I just ordered them yesterday. I'm tired of algae from low phosphates and not being able to test in the high range, it is time to get them to the right level.
