Ok so I am gonna get a small 5G tank for a betta but I am gonna start the cycle today. I was just wondering, will it matter if I add the substrate during the cycle as opposed to at the begining?
No not really, although putting it in now would help as it will have a good bacterial culture on it.
What substrate is it? If its sand, until its all settled you will have to leave the filter off. This could be about 2 days.
;- or you could leave it on, but it will clog the filter.
