I would give it time because when transporting live rock it will cause a die off of some of the organisms which can cause a spike I would give it a week or two and then start testing to make sure all your parameters are in line.
Live rock has been in a week tomorrow... been checking water regularly...also been alling Calcium, Iodine, and this other stuff my buddy at the LFS suggested. Hoping to get a clown and anemone this weekend perhaps. Also, added additional circulation via this little occilating box. The 2 snails I added are doing good, and I can find 1 of the 2 shrimp I added. I did notice some red "hair" growing on a rock though... I am getting good reef bulb tonight.
OK people...two clowns since Saturday... yay.... wake up this morning and the sand has lots of dark brown on it... is it algea? what should I do about it???
