unique setup

[Don4921]

i have been saving up for awhile now and finally am ready to create my monster tank
it will hold aproximately 720g my question though is has any one had there filtertration system on top of their tank?
like instead of underneath the tank, above the the lights or wat not
will it work the same as underneath ?
i have little room to put my system underneath the tank that is why

Years ago I maintained three built in tanks with the filter system above the tank. They work very well in the right situation but tend to be more difficult to maintain due to the location.

Move the filters off to the side.
