I personally find that the areas under the rocks/driftwood in my tanks
become dead areas that gather mulm and all sorts of other rubbish so
will periodically lift them and give the gravel a good clean with the
vac....A lot of where and how many dead areas there are in a tank are
very dependant on the water flow and circulation - for example in one of
my tanks all the dirt concentrates in just one area (near the filter
outlet) whereas others it will be under rocks and wood....

I totally agree with Gill about vacuuming under rocks and other decor.
this mulm build up can lead to decay, acid production and deplete kH. I
am careful around plants, but I try and lift up the rocks everytime I
vacuum.
