If this is not possible you will have to do a fishin cycle. You will need to test your water several times a day and do water changes several times a day. Any time your ammonia or nitrites get above 0.25ppm a water change is needed and make sure to add conditonor to your water. If your readings are high bigger water changes are needed.
For example if your ammonia is reading 1ppm doing a 50 % water change will knock it down to 0.50ppm. Wait an hour and test again and if its 0.50ppm doing another 50% will knock it down to 0.25ppm.
So basically test your water several times a day a do the size of water changes according to your readings and the half rule. When doing a water change make sure to wait an hour before testing again.
thank you, ill keep this.
