I would trust the API over the test strips.....if your worried about it take a sample to your LFS and have them triple check your results...

also what Lorenzo said can be true....Ive had a colony close up for a couple weeks for no apparent reason.....have you looked at them closely for nudis?

Now that you mention that, when I got them the other day, there was a few little slug looking things on them. About a few mm long, nude in color and had horn like things on top of their heads and on their backs.

Ummm, yup. Those are nudibranchs and are probably your culprit. Bare in mind you've had the frags for less than a week. Give them some time.

Same tank/lighting etc as my corner tank and Zoa's love it pretty much anywhere in there. On sand, halfway up. didn't matter. they got HUGE wherever they were placed
