I think you need to wait a little bit longer before getting any fish or other aquatic animals because it seems that you have not done enough research about them (no it doesn't seem, it is apparent). Not trying to be mean or anything, I'm just saying if you dont know what a sump is then you haven't read enough. Spending more time reading/researching will help save you from lots of problems down the road, like fish dying.
Btw products like Cycle are IMO
useless/unnecessary and I'm sure many people here will agree with me about that.
