What gives... no cycle at all?!?

[flaeaglefan]

ok... I set up my 220 a couple weeks ago, and put new water in 3 weeks ago. Exactly 1 week ago I added 100lbs of very mature, cured live rock, and 200lbs of live sand..The rock came from a 8 year old system that was owned by a LFS owner, and in his home tank. The rock is covered in coraline.

Anyways, I had the water tested the day after i put the rock in to see what was going on...

these were the results
Alk 7
P04 0
No3 0
Cal 250
Ph 8.2
1.030

I over shot my sg and didnt know what was up with the Calcium being 250...

So over the next couple of days, i added calcium, however i didnt add much at all. 12 teaspoons over 3 days. Which should have only risen my calcium by about 12 or so.

Today i went to 2 different LFS and had my water tested again, to see if anything changed.

Todays numbers
Alk 7
PO4 0
No3 0
Cal 450
Ph 8.1
1.027

Im begining to wonder if i will ever get a cycle due to the rock and sand.. What do you guys think?

Its possible you wont. Keep an eye on the params and wait it out just in case.

You proably wont see a cycle being that the rock you put in your tank was mature and you had little die off in the transport. I was the same way never had a cycle either. wait a week or so and press on with a CUC

You won't get a cycle if the rock that you put in your tank was cycled and it wasn't out of the water long when you put it in your tank. No die off= No cycle.
