would it be a good idea to put some smaller pieces of drift wood that would be lost in the tank in one of the sump compartments to soften the water a bit?
i am probably not going to put any large pieces in the main tank so was toying with this idea.
also my overflow hole is 1 or 1 1/4 inch, would this be able to cope with the 18 000l/h flow rate which is rated at 10 800l/h at 4 foot.

Oh oh....We have been taking someone elses work for fact without examining the data or results. Here is a statement how the chart in the link posted by Dr. Joe was formed:
Volume can not be used as a measure of surface area. They are not related. If you have a sphere and a pin, the sphere is going to have more surface area and volume than the pin. If you add enough pins to equal the volume of the sphere, the surface area of the pins will be exponentially greater than the sphere. Thus there is no relation.
Another example to think about is if a sphere with a diameter of one foot were to be considered for a 1 cubic foot filter, the open space that is wasted would be large. Now as the diameter of the sphere is reduced to allow for smaller spheres, the area will be increased and at the same time the volume of the bio-media is increased. As the diameter of the spheres is further reduced to say fine sand, the volume of the media is at a maximum while the surface area is also at a maximum. This is a direct contradiction of the statement "More volume of solid means less surface area. More volume is just taking up valuable space."
If this is the guy that made the chart, we are in trouble
