Thanks for the comments everyone!
Lisa, I thought about a water change, as I just performed one on Tuesday, but I must admit, I have been a bad first time with my little biocube. In the fresh water world, I got so used to my parms being "normal" let's say, I hadn't really tested PH in this tank :::slapping self on hand::: lesson learned though, will continue to do so.
And Lynn, I think that's what I will do, just to make sure my test hasn't gone bad, take it down to the LFS. In fact, I've heard of a newer one in town, where the guy has 18 years of salt experience, started as a hobbiest and he's turned it into an aquarium business. Supposed to have some of the best LR and critters around town. So that will be a plus there.
Thanks again everyone, I will update again when I know more of what's going on with the PH. BTW, I did NOT dose with the aragamilk today, will test first thing in the morning and see if I get the same results as today. If so, down to the LFS tomorrow evening. I've been watching my corals and critters carefully and everyone still seems content in the tank. :::shrugs and hopes it's just my test being bad:::
