My routine involves wiping down the glass inside....I like to do all the corners with a toothbrush since I can get a little crazy with razor blades in the tank at times......I basically work my way from top to bottom in the tank, and then I stir a small section of my sand bed. and then I take water from both the DT and the sump area. There is nothing wrong or harmful with stirring or vacuuming your sand bed. As long as your not disturbing your entire sand bed at 1 time your fine.
As far as my LR, it gets the same treatment as my sand....the LR gets brushed with a dedicated toothbrush for the tank, and then I have a small PH with a hose attached that I use to blow things off with.......I do run filter socks on my sump, so that helps with catching larger stuff as well.
As far as equipment used it's pretty basic....Python water hose with 24" extension tube, razor blades, toothbrush, PH, and soft damp cloth to wipe down bulbs and reflectors as well.
