| Re: My First Quarantine Tank Nitrites have stayed high the last 5 days or so - in the 25 range - and they started to slowly drop - down to 15.
The other night I was making some new seafood slurry (shrimp, clam, and squid in a blender and frozen into tiny RO/Di ice cubes) and I took a large piece of squid and placed in the the tank. In the morning the water was very cloudy and smelly so I removed the big piece of squid. Free ammonia was at .2 and total ammonia was at 3.0 while nitrites were back over 25.
12 hours later NH3 was back to 0, NH4 was down to 1 but my stubborn NO2 remained over 25.
My ammonia consuming bacteria is doing a great job but the nitrite consuming bacteria are remaining slackers!
I did add some much smaller fresh squid pieces to feed the bacteria.
Today is day 18 of the cycle. |
