Just make sure you cleared this with customs... Im from Manila... and just got back in Seattle from a month vacation. Customs are very critical with liquid... any sort of liquid, even if its processed, canned or bottled. If you are thinking of bringing live rock back here, then you have two issues... one with water, since you need that wet to keep everything alive (most of the time wrapped with wet newspaper or clean paper). And another issue is with the inhabitants, since you are bringing in live rock. They will be considered "live" thus needs to be quarantined, examinied for banned pests, organism and what not.
I suggest that you just bring in dry base rock and just seed it here with live rock. its cheaper, weighs lighter and less hassle to customs.
just my 2 cents.
