Back wall cleaning, shadow box and other new tank concerns

[Eleni18]

Hi all. I am thinking of upgrading from my 250 liter tank to a 450-500 liter one, maybe with a sump. It will have to go against the back wall under the stairs from living room to bedrooms and I am worried as to how I might clean the back glass wall as it would be impossible to have access from the back and ceiling space on one side would be quite cramped as well. How do you clean your back walls, those who do? And please don't tell me not to, because on one hand I like the look of really clean glass, on the other hand I have seen a fabulous thread on making a shadow box background and this really means the glass has to be clean. Thanks for any ideas.

I use a kitchen scrub brush. Otherwise don’t clean it.
