Turning Wet/Dry into Sump

[magyk]

is it possible to turn a wet dry for a 150 gallon tank into a sump??
I would obviously take out the bio balls and just have the water come down.
Has anyone done this or heard of doing it?

Do a search on this forum on "wet/dry to sump" you will get lots of information on this. I am new to this scene but from what I have seen so far, its pretty common.

It can be done, just remember to remove the bio balls slowly over several weeks time, to change the load of bacteria that they are carrying onto the liverock and livesand.
Are you going to keep the prefilter?
