A little bit of water and a razor blade and maybe 10 minutes of elbow grease .. yeah, I can see that being a drag.
My excuse for my 280g is not the removal .. it's more the putting-back-on now that I have running tanks in the tank room. I'd rather not spray at all actually, which limits the choice to something roll on, or a removable background. Totally doable and there's no excuse that I don't do it other than as a purely cosmetic issue it takes a lower priority than a couple other projects on the go...
Do it!!!
