Thank to you both, we took a sample of the water to LFS
and they tested it and it was 0.25 so it confirmed what our last test showed. We got one of those gage things that stay in the water, it shows safe, but then I guess it considers 0.25 safe, we are still going to test though, but not use the test tubes that came with the AP kit. The Reef lab kit has different tubes which seems to give more of an accurate reading.
So I understand what you are saying about the live rock , so is that why the nitrate readings we had zeroed out and now the ammonia which was at 0 is back up? Now we aren't going to have to wait to see if the nitrate spikes again do we? It's been 0 at close to 2 weeks, it's just the ammonia that went high and is now climbing down.
