Hmmm I would suggest googling all the items that you are questioning, there are a lot of various types of systems that you can put together from fish only, fish only with live rock, reef systems and those are only what you keep in it, let alone how the system is set up. Various types of setup don't even have a sump or mechanical filtering, some use all kinds of filtering and skimming. There are may ways to set up a marine tank. Keep reading everything you can find on the internet (and take most of it with a grain of salt, there are just as many oppinions out there as there are ummm fish, yeah fish!) |
