I will say that me installing a UV sterilizer during the cycling process has delayed my cycle.. I have a 30 Gallon tank and its now about 3 months old... Took out the UV Sterilizer and now Tank seems to be magically cycled after 4 days removed. I have done reserach on this matter and lots of experts state that it wont effect it and some say it will. I believe it did. I would suggest removing it to anyone that starting up a tank.
