I don't mean to disagree, but i hear a lot of people saying to spot clean and clean their entire viv once a month. I have read some caresheets, such as the one from Petco, that claim you only need to fully clean the tank every two months. I know it's better to clean it every month, which is what i'll probably do, but are you people saying every month as a suggestion. Or are you saying any longer than a month is way too long to be leaving a "dirty" tank?
