Let me start from the beginning......
A long time ago, I had a beautiful fish only tank. a few docroative rocks and a Puka (?) shell base. Basic lights that come with the first hood you would buy. Never had one problem. I move to a new house. I take my 10 or so fisha nd put them in a small 20 gal tank at a freinds house so I could move the tank to its noew location. During the move, the friends house as an electric surge (we think) but all the fish die. I set back up the tank, get it going again, and then take a job where I was on the road mon-fri. No one at home to take care of tank..it goes to hell. With the little time that I have during the wekends, i decide that I want a coral tank and start buying those. ( I upgraded the lighting and brought in the live rock in the process). Travel some more, and again, everything goes to hell. (I am no longer at that job anI am no longer at that job and starting to get back in to this hobby again.)
The short answer to your question is that there were NO fish, and two small mushrooms in the tank. I was so frustrated at how it looked that I just broke it down and cleaned it off and am basically starting from scratch. i just added in the five fish so the water could start to cycle.
Now that I have found this web site, I am hoping to learn how to do things the right way by talking to all of you. I want to slowly build up my tank again so it looks the way it did when I first started.
Truth be told, I never paid any attention to things like water tests. It has been a VERY expensive lesson for me, but now that I have time to build it back up again, I plan on listening to my new found friends here on this site.
