I know what chart you're talking about and I think it's more meant to show what a typical cycle looks like. The actual numbers, in my opinion, don't really mean much. It all depends on how you cycle your tank, how much ammonia source you put it to start with, etc. When I first cycled my QT tank (10g), I threw in a whole raw shrimp. That was waaaaaay too much! Stunk like crazy and my ammonia shot up above 6ppm, if I remember correctly. The second time I cycled it, I got smart and just used fish food. Ammonia only went up to 1ppm. It just depends on how you cycle it.
I now understand the "upgrade" issue. From your other post, it sounded like you were going to put that fish that's in your QT in the main tank only after a couple days. I guess I assumed it already had live rock, etc. Yeah... that stuff can get pricey. I have no idea about mangroves, so I'll let someone else tackle that.
Regarding the deep sand bed (DSB
), technically, DSBs are normally considered 6" deep. That's going to take up a fair amount in a 10g. My sand bed is minimum 4" in places, and it seems to work OK as a DSB
. Even then, that's still a lot of space for a 10g.
