Not a normal cycling question.

Not sure where to start.........I set up a 120g tank in early december with dry rock (it seemed extremely clean) dry sand and two tiny pieces of live rock and a few cups of live sand (maybe not live but it was "live bag sand") due to a mother load of reasons i was not able to really watch the tank the first few months. I had the skimmer going and the lights turned off for the first few months and when i tested all the levels they read zero. So in month three I added a little goby to the tank, tank sat of two months after that.

Well over the past month i have finally had more time to spend maintaining the tank and it has still never had a reading over 0 nitrate, nitrite, ammonia nothing. There has not even been algae other than on the tiny pieces of live rock that where in the tank, they grew some green algae but its almost gone now. All the other dry rock still looks perfect and white. It has now been six months since that tank has been fully running.

DID MY TANK EVER CYCLE is the questions, be it a dumb one thats still what im asking.

i dont put much stock in the bagged live sand. i think you should grab 1 good chunck of live rock from some where and throw a raw shrimp from the supermarket in there.
what happened to the goby?

the goby is alive and well, i could do what you said but im still not sure if the tank cycled are not. Until i rule that out i cant really do anything because there are two fish in there.

The fish take over the for the shrimp. The shrimp is to make the bacteria populate. Two fish can handle it. I would add a good size piece of mature cured live rock and see what happens but I'm guessing your tank is already cycled and well

 

[manhorsedog]

yeah i would guess the same thing, its just strange how the rocks still look so clean.

rocks may look clean b/c you never ran any lights? I'd say give it more time run a regular light cycle, it can take time to get your rocks to purple up
