I just dodged a bullet similar to this. I bought 7 lbs of dry rock from my LFS
and began plunking pieces in the DT. I got to one that looked a little funny (had some brown stuff on it) and decided to boil it. After I boiled it, it had this awful stench to it. I wasnt sure what the heck it was (thought the brown stuff was just dirt) so I put it into a bucket full of old tank water. A few days later, AMMONIA OFF THE CHARTS!!! YIKES!
The rest of the rocks are all sitting in the bucket. Im guessing the rocks I added already are okay as nothing bad happened. (WHich Im sure would have )
I dont really want to cure the rocks (as in, wait for good bacteria to show up), I just want to get rid of the decay. Is this okay? My tank has been up and running (cycled) for 11 months now. Im just adding rocks to the tank.
Is it okay to keep doing water changes until the ammonia is at zero? Seems letting whatever rot for a little while would be faster than waiting for a cycle. Plus, I dont have any extra power heads. The rocks are just sitting in a bucket of old tank water. Each time I do a PWC
on the DT, I use that water to replace the bucket water.
