Awesome! Thanks for being a sponsor!

I love my Hanna checkers.

 

[SalinFL]

Fantastic! Welcome, it's great to see you here. Just got through with a water change using my refractometer. Don't know how I made it through so many years without one. Thank you for a quality product.

I already own two checkers where is the nitrate? Hehehe

Thanks for being a valued Hanna customer!

A nitrate Checker was worked on in the past by our research and development department but due to repeatability and accuracy concerns we were not confident to release it to market. There are many interference when preforming colorimetric analysis of nitrate in seawater. We will continue to look into this project and the best way to stay updated is to sign up to our blog where we will keep you updated on all new projects!

Thanks!

Welcome!

Always wanted an 'official' answer on this:

I know BRS has done a compare of the phosphorus vs phosphate checker...for just getting a ballpark on "are my phosphates high or not?", I should be good with the phosphate checker, right? I use it, always get 0.00, which I take to mean, I'm probably ok and no reason to run and grab the GFO.

My most advanced corals are montis.

LOVE my alk checker, use it daily.

The HI713 Low Range Phosphate Checker has an accuracy rating of ±0.04 ppm ±4% of reading and a range of 0-2.50 ppm. This means that is you are reading 0.00ppm phosphates then your levels could actually be 0.04ppm, which is perfectly fine for SPS corals. The HI736 ULR Phosphorus Checker measures in parts per billion and has a range of 0-200ppb Phosphorus, which translates to 0.003-0.613ppm phosphate. So if you want higher accuracy at lower ranges then go with the HI736 but the HI713 will work for measuring low phosphates as well. If you are trying to keep your levels below 0.05ppm then you are ok with not using GFO, but if you notice increases just remember the accuracy rating of the HI713 Low Range Phosphate Checker.

Thank you for becoming a sponsor to the r2r community!

Just out of curiosity. I was browsing through the Hanna webpage and noticed how many checkers there are. Is there a difference between the glass test tubes for each checker? From what I noticed they all use the light method to test the water. What is the difference for each checker?

All the Checkers are handheld colorimeters which use light to measure absorbance of a certain ion concentration. They all are single parameter measurements. The Checkers, except our maple syrup Checker, all use the same cuvettes. The difference between them is what chemical parameter they are measuring, the range, the light wave length, Chemical method of analysis and color of the Checker. So for example, our HI736 Ultra Low Range Phosphorus Checker uses adaptation of the Standard Methods for the Examination of Water and Wastewater, 20th edition, Ascorbic-Acid method LED @ 525 nm wavelenth, while the HI758 Calcium Checker uses an adaptation of the Zincon method @ 610 LED nm wavelength.

Its important to note that not all Checkers will work in seawater, because the range is not correct for testing parameters and there is interference preventing proper analysis.

I understand all this but let's say swap out one of my alkalinity dkh cuvettes for a maple sugar one Cuvettes. Would that make the test in accurate because of use a different cuvette vs the one that comes with it? So essentially the only thing that would be different Would be the cuvettes.
Thank you for the help

Isn't it nice having Hanna here to answer questions? HA!
