Red Sea KH test faulty?

[Ramon Estevez]

So I spent the money on the Red Sea Test kit and every time I’ve done the Alk test it has a faulty color change every time. I guess it’s Back to Salifert wish I didn’t waste the money... Idk if the titration needle is faulty or if it’s the actual titrant.

It's not a certain color that your looking for, but the endpoint change of color.
Could be pinkish, redish or a peachy-orange endpoint.

I use the Hanna Alk Checker and love it

I was told it should be a red...

When you see it change to an endpoint color, add one more drop and take your reading.

RedSeaKev taught me how to use it and Red Sea needs to fix the old video

Heck,
I went with the Hanna and never going back to color readings on alk.

For alk API is pretty darn good too

Did it not come with directions?

IIRC, they recently changed the kit.

It happens over time. Usually due to exposure to the air. Once there is a change in the endpoint color that should be your reading. If you just bought it recently I'd contact Red Sea or whomever you purchased it from. They'll usually send you a replacement.
