You are definitely going with a better option.....i dont care what anyone says..cleaning my 4 ft tall is quite the task.i have to yse a 4ft step stool everytime and still a good portion of my body is in leaning inside when i acrub algae. Ive tried many of the extendable handle type algae scrubbers and blades and the problem with them is that when its extended that long it is not that stiff...it has flex to it and you have bvb to put sone good force into it get into some spots. Also simple things like gravel vac and even netting uneaten food or fish becomes a million times harder..stick with the 10 ft tank if u have mobilty issues for sure
