And my tank water now as it stands is Amonia 0.50 Nitrite 1.0 Nitrate 0.50 PH 8.2
The tank has been up and running for 3 weeks now. Ammonia and Nitrates has remain consisiant and hasnt moved for over a week but Nitrites are slowly rising. Like i said before, i think adding cemicals to deal with the Columnaris messed things up abit.
If you are worried about the meds/chemicals you have added to your tank interfering with the cycle then add some activated carbon to the filter media, this will remove any medication in the tank.
Once the tank is cycled (a long journey) it is time to think about the Columnaris. personaly i think it will be long gone by then.
