I mean every tank is different and I guess you know and can read your tank better than anyone else. All I can say is for my tanks, I have always run the skimmer right from day 1 and never had any problems to complain about. Other will say that you don't need to run the skimmer at all during the cycle. I guess I would suggest that if it works, don't fix it and stick to the methods that you seem to have the best success with.
