I have a 20 gallon long tank, which I spot clean every day. Change water, take out any feces or urine, I add and subtract substrate at least once a week (coco fiber substrate) and I completely clean and sanitize once a month. Now I made a rack with tubs, and was curious if the same cleaning schedule can apply to them or do they need to be cleaned more often because they hold humidity better. In the near future I may be switching to aspen substrate, I'm just worried about the tubs needing more cleanings. Anyone have any ideas?
