Ya, I think it got a little off track. Changes during cycling was the topic. I dunno, all i can speak with is from me experiences and I have had tanks set up since I was 18, so I guess you can say I have dabbled in the hobby for 19 years. When it come to cycling a tank I have never done a water change until after the whole cycle is complete. And everyone knows, people ask for advice when it comes to the cycling process but how many actually listen or take any? They will do what they want and how they think it should be. Then complain after the process when they have huge algae blooms and cant get rid of it. To each their own but I still see no need to do any type of water change until after the cycle has completed, again this is just my opinion. I forgot to mention the peeing in the tank one. My one buddy actually did cycle a tank after peeing in a cup and pouring it in his tank without any problem. I dont recommened doing it but it did work.
