Haha I figured that well I won't give up that's for sure also is it normal for a pulsing Xenia to close when the lights go out?? Sorry about all the questions

Questions are good, its the ones that don't ask that are the trouble.... ;)

most coral close when lights go out, some of it is for protection, others its because they have gotten enough light, while others shift shape and produce sweepers, LPS corals do this a lot.

here is what it looks like, they will catch food, and sting/kill other coral too close.

thats about what I figured....

API test kits will let you know if your way above, or below (most of the time), but when it "off" ± .2 I would not worry too much, but get some tests done with another kit before any action is done to "correct" it.

the best thing to do is look at your coral, if they are happy, then there is a good chance your test kit is bad, and even the best test kits have been dead wrong, and I mean dead as in a tank(s) crashed from it... :(
