Hello everyone...I purchased what i believe is around a 30 gallon square tank that has been sitting for awhile. It came with a reef octopus skimmer and a live rock and sand that has been sitting in a tote with saltwater in a basement for about a year. I now have the sand and rock in the tank, but im trying to figure out how to assemble the skimmer. if theirs anything i should do first please let me know im new to all of this.
