Getting to the bottom is especially true of tanks in any species!Unfortunately dust,debris,food,and such stick to aquarium sealant so unless a tank is acrylic(molecular bond,not sealed but still leak proof)it will need to get that part cleaned during cleanings which means disturbing the substrate at least along the edges.I find the best way to clean sealant is just using a wet cloth you don't mind getting rid of or an extremely strong paper towel(I found out the hard way cheap ones just don't hold up)and just wiping the sealant.
