Before you say I am crazy, I "inherited" the fine equipment and tank. I am using an expert to help me get started and will have her maintain the tank until I have acquired the necessary skills. Tank and its residents' health come first. As soon as I get the specifications I'll list them in my profile. I'll post pictures of what I have so far. About the tank, it has a central overflow column (could be set up as 360 degree, but I have it about 18 inches from a wall). Sealife Systems wet/dry with bioballs filtration, two apparently powerful output heads, two panels of a total of 4 Actinic lights (two white, two blue in color). There was a reticulated eel that I has getting but it got out and died before the tank's move to my home was completed. I've started from a cleaned out tank and am using live sand (1-2" estimated), small amount (4 or 5 live rock), and decorative rock and coral. Plan a reef (fish and coral, no eel) set up. My background is that I am a biologist and conservationist who hasn't dared until recently to try to maintain a salt water tank. I am excited about my new adventure.
