You are definitely "on the right track here"!
The poor circulation may cause the odor which I referenced in my 1st post.
If you are not overfeeding then with your stocking level you may never observe ammonia or nitrite concentrations (they will exist but not at levels commonly detectable by fish keepers).
I am saying this because if you do not observe ammonia or nitrite concentrations then IMHO I would not do a water change as these very small concentrations are providing nutrients for the growth of the ammonia and nitrite digestion bacteria in you biological filtration media.

Short funny here.
When I purchased my aquarium I spent the extra $'s for a 30" deep aquarium in order to grow angels to full size adults.
My aquarium is acrylic with access hatches in the top.
I never thought ahead that my fully extended arm with a shoulder as far in the access hatch as it would go would allow my hand to be of use on approximately 26" deep in the tank.
I now have several utensils which assist me but working on the bottom is still at best an ordeal (this situation is exacerbated by the lack of bottom visibility due the rocks, wood and plants).
I have also tried some "Southern Engineered" approaches such as your coat hanger and I do not remember one which did not cause more grief in addition to not fixing the problem they were intended to sove.
