First of all, I'm new here, this is my first post and the sight is great! I have had my 75 gallon for about five years until a couple of years ago when a hurricane came through and the battery backup on my tank died and everything died. I am in the process of rebuilding now but had some things I want some input on. I've always ran an overflow box into a 75 gallon wet/dry sump system. I have a protein skimmer also. I was thinking about modifying the sump to convert it into a fefugium of sorts. \n \nThis is the plan:\n[IMG]http://i15.photobucket.com/albums/a386/dccylwsdime/DSC00004mod.jpg[/IMG]\n[IMG]http://i15.photobucket.com/albums/a386/dccylwsdime/DSC00003.jpg[/IMG]\nThis is my skimmer and return pump. I'm still wondering who invited my son into the picture.......not I!
