No need to get an OTO test online (but do order a K-2006). OTO is available almost anywhere pool stuff is sold. It's the yellow drops in the Red/Yellow drops kits - Pools store, wall mart, Home Depot, etc.

What Chem Geek was suggesting and I was seconding was that you might have extremely high chlorine level. So high that the chlorine / bromine tests are getting bleached out. OTO doesn't bleach out and will read yellow to orange to brown as chlorine / bromine concentration gets very high.

By Chem Geek's estimate, you've added about 460ppm chlorine to your pool. That's quite alot. If the CYA wasn't greater than 100 then there wasn't enough to become the chlorine demand you're seeing through conversion to ammonia.

You really need a definitive test (OTO) for extremely high chlorine.
