Is it possible to have a tank with just a filter. or will i need some sort of circulation system in place such as a sump. My local guy is directing me to the Marineland emperor 400 and he said that should be more than enough to keep my tank going without external parts.
Kevin, the most important filtration is your live rock. You should have 1 to 1.5 lbs per gallon.
Flow is very important in your tank. You should have between 20-40 times your tank volume in gph.
A sump's key function really is to allow you to put skimmers, heaters hang on filters like your emperor400 etc in it or on it so they are not hanging all over the display tank.
There are of course many other functions of a sump but in your case you don't need one to have adequate filtration.
What you make think of purchasing is a protein skimmer which would give you alot more filtration then the marineland emperor400
