Is it the redsea pro ?

There is a high range & low range method. The low range is performed using 100% tank water.
The high range is performed using 1ml of tank water to 15ml of RODI water.

It is the pro. Here's the dial.

I always used 100% tank water.

My God.......I always thought I had no nitrate.

Oh man, that sucks. Learn something new every day! Gotta love this hobby!

Oh well.....I have no algae and lps look great. 13ppm isn't that bad.

No its not. But a bit lower is better.

True, but I'm more concerned about phosphate. My hanna read .03 and the ati came back right on the money.

so why are you concerned ?

 

[Docdiggy]

Because I was dosing sodium nitrate for a while to get my nitrates to what I thought was 5ppm. I didn't realize I was on the high range.

I have been working on Nitrate Test Development for quite a while ....Here is a link to my work using the Hanna Phosphorous Checker HI-736....

In this posting there is also a link to previous work

I am currently working on a test using the HI-764 Nitrite ULR......This one seems to give better precision and accuracy as well as expands the measurement range...I essentially used the same development method as I did in the previous work only using the HI_764 as the measuring instrument...I am testing two separate regression models to see which one works the best...Hoping to post my results soon..
