False Postitive?

No, not my wife's pregnancy test, we're done with those.

I'm using the API test kit and, with two different test kits, the ammonia reads at .5. Nitrites is 0 and Nitrates are at 10.

So, is it possible that the test kits are giving me a false positive on the ammonia?

In the tank now is about 25lbs of LR and one yellow tail damsel, about 1.5" long. I feed 3-4 pellets twice a day and watch the little fella eat two before I have to turn my attention to my children.

Filtration is a Fluval 405 can and I have a Hydor reef kit 600, 2 power heads, going.

Oh and the tank is a 29 bow front

Anything is possible, but test daily and see what you get. You could also bring a sample to your LFS if you want an answer more quickly.

API is known to give false ammonia readings

Make a small amount of fresh saltwater and test it against that. It should have 0 ammonia in it. If it reads zero, your kit should be working properly.

+1

but usually it is the lowest reading of .25. .5 may indicate some ammonia.

Would there be any need for concern? If it doesn't go up, according to my test kits, should I worry about it?
