I’m new here but been doing a reef tank for about a year now. I started with a fluVal 13.5 gallon, bumped up to a 55 gallon, and now I have a 180 gallon bow front tank. I do not know enough about anything but willing to learn as I go! Found this site and so far I’m impressed on the help and advice. I bought my 180 used fully ready to go which was a plus for me.
