I switched from a 200 gallon to a 120 gallon so as to control the height
out
of safety concerns of the glass shattering. All the water, fishes, LR/LS
from the original tank has gone into the new one.

However, upon testing I find that suddenly ammonia and nitrite readings
have
occured. So far, .5 on both counts. Cant understand why that shld be so as
nothing new was added. Have restarted the Eheim wet/dry to control these
but
am baffled and concerned that these may go out of control and kill all my
fish!

Any advice appreciated,

Thanks,
Ajay



This is normal.

Just moving live rock and putting a piece in upside down upsets the balance.
There are different concentrations and types of bacteria top and bottom.
They need to readjust. Some thins die....ammonia goes up a bit.

I'm no expert. If someone advises different.....take their advice......this
is just my understanding and experience.

Add some mangroves. 1 per 10 gallons and you can dump ammonia in
there.
