I am trying to quickly cycle my 20 gallon so I can move my betta in when he recovers from fin rot. I know how to cycle, but I want to speed up the process with some bottled bacteria. Which kind is the best to get? I've heard that Tetra Safestart and Seachem Stability are both good so I'm trying to decide between them. Have any of you used either one and if you did, how did it work for you?
