filtration yes sump is better then a canister and your canister is better than your hang on filters you have. skimmer is not as important unless you are afraid of over feeding(heard this from people that have been in the scene for years) but remember to turn it off every so often so it is not being over worked. just try not to get hooked and put a whole lot of stuff in at once. do your homework on what you want to get to see difficulty of keeping and how to feed ask questions and don't always believe what some people say cause they might think they know a lot when they have been in it for a short while so take your time on it and go slow and shop around you might find a better deal at other places.
