Rock Cycling

[Nigel35]

In June, I put some live rock to cycle into a Home Depot bucket, threw a small pump and heater and let it sit... for months. I topped off with mostly salt and RO water. I had wanted to add rock to my aquascape after selling some corals that were imbedded into the rock. Recently tested the water and it came up with great results 0 ammonia and 0 nitrites, 5 nitrates. By pure luck, I forgot to refill the bucket after going on a trip. The pump burned out and the rock was exposed for a few days... Refilled the bucket just today and am getting a new powerhead. I was originally planning to add the rock to the DT after I got back, but I am quite hesitant to add it after some of the rock being exposed to the air, not dried out but lightly damp. Would my terrible mistake result in me having to re-cycle the rock? Also any advice when the time comes to put the rock in the tank appreciated.

Cheers,

Nigel

If the rocks where damp I imagine any die off would be little only, the flow I’m not so sure. But maybe wait a little longer and re test

Yes you need to recycle. But the recycle time will be a lot shorter. Also when you add to display tank add a little at a time and check parameters.

Im thinking about giving it another 3-4 weeks, does that sound about right?

It may not take that long. The only way you will know if it has cycled is to test the ammonia, nitrite and nitrate. You could add a little ammonia as food for the bacteria and see what they do with it. If they can utilize it down to nitrate then the rock is ready.
