I am fully prepared to put on my snorkel gear whenever I need to do maintenance. Cant agree more with having the extra dimensions worth the pain in maintenance.My tank glass is 90 cm high... I use long Tunze tongs with the grip at the end (get two in case you drop one!). A dive mask helps you see into the water from above better.
And something high to stand on so you lean over the tank.
It does make things more complicated. But for me it's worth it: I love the extra dimension you get with the top to bottom depth.
