nice to meet you all!!
we have a a truck with a power-tailgate, and we were able to pump out 90% of the water into 45 gal drums.
live rock and fish in one drum.

so everything is all back together now, except the hob skimmer is not setup yet(needs one helluva cleaning) , the sand needs vacuuming really bad, and im sure the xp4 is pretty damn dirty too.

what should i make priority to clean first?? skimmer or filter??
and just part of the filter now then wait a while then do the other part??

funny part is , i have no idea what kind of fish i have!!!
