Hi again
I starte to change 25% of the water on both tank.
My reading for tank 1 is
ammonia 0
nitrite 2
nitrate 2
Hp 7.5

Tank 2:
Ammonia 0
Nitrite 2
Nitrate 5
Hp 7.5

Should I kept changing the water.
in the past, I had the gave the fish some med. Could that be the reason that the cycle is off

Lucy

If there's fish in the tank, yes, continue doing daily water changes until the cycle is complete.
Yep, Some meds effect the cycle.

Rita

yes there is fish in the tank
and
thank you for the info

Lucy

Your welcome, good luck. Hope everyone does well.

Rita I would consider doing two or three times a day partial water changes (say every twelve or eight hours) to bring down nitrites close to 0.5ppm since at 1ppm it's likely too much for the fish. Problem is a sudden change could also harm them...

Best of luck Rita.
