So I have an AIO 40B and a minimalist stand with nowhere to hide a ton of extra equipment/wires/hoses. I was picturing a 3 chamber reservoir that could hang on the back behind my AIO overflows that could hold maybe 2 gallons of RO/DI and 1/4 gallon of each Alk/Cal. Is this feasible without stressing the glass too much? Anyone have any clever ways of securing top off containers or dosing containers without sticking them at ground level?
