Hi everyone! We, my husband and I have decided that we would benefit from being a part of this site since we are constantly looking up information and it seem as if we search for hours to only find the basics. We recently set up a 55 gallon saltwater aquarium and everything seems to be running very smoothly. We have all the necessary live sand, live rock, filtration, skimmer...and such that is needed. We have had a lot of luck with the reef and fish we have placed in so far...that is up until today!
