Red Sea Pro Nitrate Test - High Range?

[bdare]

Hello all,

I just received my Red Sea Pro Nitrate test kit. The kit says to pull 16mL of tank water into the test vial unless you're doing high range. Then you use 1ml of tank water and 15mls of RO.

What the kit fails to mention is how to calculate the result. Do I simply multiply by 15? Seems odd to go straight from 16mls of tank water to 1.

The chart shows hi and low matches to the color wheel

Yep! Just have to read the directions in greater detail! Thanks.

Glad you figured it out

Gonna piggy back on my own post... I'm trying to read the colors but they seem like different shades.... is it just darker than the card or a differ ent color?

Different shades of the same color.

Different shades of the same color.

Thanks. I'm color blind... So... darker than the reference? Meaning my nitrates are STILL higher than 64?

Been dosing 60ml of DIY Nopox on 250 gallons total volume.

I don't know how to read the disk since it seems to have 0.00 in an odd place, but the middle one looks darker than any on the outer ring. Not a lot darker than the darkest two, but I don't know how the color responds at that range.

how do we read this kit?

The chart shows lighter to darker in a linear scale. But the wheel makes no sense to me??? The lighter colors are 1ppm and 2ppm, but zero is darker, then 0.25 is even darker, and 0.5 is even darker than that???

not my test pics, but my card and wheel look the same and i reconcile to the two scales...

I ditched this test. Went back to salifert and just ordered a nyos. The Red Sea takes too long and is too hard to read IMO.

i can read the color fine.. I just don't know what the color represents because its seems to represent different things on the card then on the wheel?

Just depends if you added RO and are doing the high range or not.

Look at the card and the wheel. Compare. The wheel is not linear. But the card is? I am not diluting. What ppm do i have at the second to lowest shade of color?

 

[bdare]

They way you have the wheel now it's reading 4ppm.

 

[Mywifeisgunnakillme]

the wheel above is not my pic... I just copied it from the prior post. My reading is second to lightest shade on the wheel. What ppm is that?

2ppm

 

[Mywifeisgunnakillme]

same color two readings... I did not dilute.... what is my ppm?

 

[Mywifeisgunnakillme]

2ppm

what's the deal with the card? does the card not say 0.5ppm and the wheel say 2ppm for the same color?

 

[Mywifeisgunnakillme]

2ppm

thank you! do understand my question above too though?

I do not see the issue.

The color in a nitrate kits gets more intense/darker as the nitrate rises.

You do understand that the number on the wheel is opposite the color, right? Not next to it. Stupid design, IMO, but it is what it is. lol
