Product Questions

I'm confused about the Nitrate test in this particular kit. The product specs list the Nitrate test as having a range of 0-250ppm. But the color chart in my kit only shows from 0-50ppm.

Over the last seven months, I've observed results of 50+ppm (the color matches [exceeds] the darkest swatch).
However, my LFS has always tested my water as being "acceptable" for fish and softies.

After viewing the recent "BRStv Investigates: How accurate are nitrate test kits...", I decided to try the NYOS Nitrate kit. And it shows a very clear 25ppm. Not great, but obviously far off from the Red Sea test.

Should I assume the Red Sea Nitrate test is fubar?

I appreciate your knowledge and insight.

Typically their tests are very good, but it does sound like there may be an issue with the nitrate test you got from Red Sea. As levels much above 50ppm can cause chronic health issues in coral and fish, they are more concerned with testing and monitoring levels within that range. Their instructions do have this to say for higher levels: "High Range: For levels of Nitrate above 50 ppm dilute 1 ml of the water to be
tested with 4 ml of RO water. Multiply the result by 5 for true nitrate level. "

Hope this helps!
