Answer 1

That depends on why your water is turning brown.  It could be a diatom problem which really has nothing to do with the  filter type.  Here is a good site toread.

Do you have any driftwoods in the tank?  Tannens can leach from the wood if it is not properly prepared.

Answer 2

as you have a large tank i'd go for an external filter, the onei use is by eheim, also to help clean the substrate get a vacume pump with a filter attached, this sucks up the gravrl or sand and the weight of it stops it going up the tube, it swirls and is cleaned, in the tube.Hope this helps you out.

Answer 3

get a external filter which you can keep clean without having to disturb the bottom of the tank.hope this helps
