So I thought my 55 gallon was cycled readings were good for about 2 week then I did a 25% water change.. Changed out the filter pads not the black sponges but the ones u change weekly during cycle I hadn't changed them... But after the cleaning of tank/ water change I'm now getting ammo and nitrite readings... What should I do
