Too much mulm can be bad as well, this cleaning and restoring the gravel in
some sections with high flish loads helps.
If you have a good case of algae and have neglected the tank for
awhile.............this is a good idea.

I forgo any bleach treatments these days but it's okay for some folks and
I just trim and leave some algae on some plants and slowly remove it if the
main issue is addressed.
If the infestation is serious and many plants, then I might do the bleach

I do like the dip using bleach better than H2O2.
H2O2 you can use in the tank so it has a few more situations where it's
more appropriate vs bleach.  

I'll do a good rework and uprooting of each section once every month or two.
There is no real set and forget substrate over the longer term, I think
most CO2 enriched tank will benefits from a peroidic gravel vacuuming
perhaps yearly in 1/3-1/4 sections over the course of 3-4 weeks
before/during the water change.

Substrate can be a lot like sewers, no one thinks too mucgh about till
something goes wrong:-)

The excess organic carbon that you remove, can cause things to go too
anaerobic and reductive, also, all that mulm/organic waste takes bacteria
to break it down, that bacteria removes the O2, that's what is causing the
more intense reduction and drains the O2 from the water column.

A little is okay, a lot is bad.

This also makes it harder on roots, they need O2 as well. 

If you remove all the organic mulm/carbon waste, then that can dramatically
improve the O2, the bioload, improve reduction to where it should be, and
beat up the surfaces where algae like to attach.
Algae like mulm in high amounts IME/IMO.
But adding mulm to a new tank is great to start things, after a year or so,
you might consider a good uprrooting of a section and see how it helps.

This methiod of vacuuming and stirring up the gravel to remove and reduce
this mulm works with some substrates, others with lots of peat, layered,
soils, jobes etc all added, these are not good for this.

The nice thing about a gravel rework is that you a chance to re slope the
That improves the look and maintains the set up nicely, something folks
that aquascape a lot might want to add to their mainteance routines:-)
